VersionEye Maven Plugin

The maven plugin for VersionEye helps you to create/update a project at VersionEye, which is a Notification System for Software Libraries. It will help you to keep your projects up-to-date and automatically notify you about outdated dependencies and license violations. You can check it out here: www.versioneye.com.

Minimum Requirement

We at VersionEye are using LetsEncrypt for our SSL certificates. Old Java versions don't support that certificate. The minimum required version is 8u101. More details on StackOverflow.

Install binary

The VersionEye Maven plugin is available on the Maven Central Repository. That means Maven will find it automatically, without adding any other repositories! And you can find the project on bintray as well.

Switch to the project where you want to use this plugin. You can add the plugin to your project by adding this snippet to your pom.xml file.

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
    </plugin>
  </plugins>
</build>

The versioneye-maven-plugin is tested against Maven 3.3.9. If you are using Maven 3.0.5 or older you should use the versioneye-maven-plugin version 2.0.1.

Alternatively you can add versioneye to the plugin group search path. You do this by adding

<pluginGroups>
  <pluginGroup>com.versioneye</pluginGroup>
</pluginGroups>

to the user's Maven settings file (~/.m2/settings.xml). This will allow to use the versioneye:* command line goals interactively in all projects.

Install from source

If you wanna install the plugin from source, you have to follow this steps.

git clone https://github.com/versioneye/versioneye_maven_plugin.git

Switch to the root directory of the project:

cd versioneye_maven_plugin

And install it in your local maven repository:

mvn clean install

Now the plugin is installed on your local machine!

Getting Started

You can check out all goals like this

mvn versioneye:help

That will output all possible goals on the versioneye plugin.

Now you can check if the VersionEye API is available:

mvn versioneye:ping

That should return an output like this:

{"success":true,"message":"pong"}

Now try this:

mvn versioneye:list

That will get you a list with all your direct and recursive dependencies and it will tell you how many dependencies you have in your project altogether.

Here you can convert your pom.xml to a pom.json

mvn versioneye:json

It will take all your direct dependencies and convert them into /target/pom.json. This is just for fun! You don't really need it, but I thought it's fun to write a small pom.xml to pom.json converter :-)

API Key

This plugin can push your dependencies to the VersionEye API, create a project at VersionEye and tell you which of your dependencies are outdated. VersionEye will automatically check your project and notify you about outdated dependencies. You can use some of the resources at the VersionEye API without an API KEY, but for the project resource you need one. If you are signed up you can find your API KEY in your organisation under this structure: https://www.versioneye.com/organisations/<YOUR_ORGANISATION>/apikey.

Now let the versioneye-maven-plugin know what your API KEY is.

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <apiKey>MY_SECRET_API_KEY</apiKey>
        <organisation>YOUR_ORGANISATION</organisation>
        <team>Owners</team>
      </configuration>
    </plugin>
  </plugins>
</build>

If you don't want to store the api key in the pom.xml, alternatively you can store it in a versioneye.properties file.

echo "api_key=YOUR_API_KEY" > versioneye.properties

If the API Key is not set directly in the pom.xml file, the versioneye-maven-plugin will try to fetch the API Key from the versioneye.properties file and it will look up the file in this places:

/src/qa/resources/versioneye.properties

If it can't find the file there it will look it up at this place:

src/main/resources/versioneye.properties

If you want so you can configure another place for the versioneye.properties file. Just set the path explicitly in the pom.xml on the versioneye plugin configuration:

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <propertiesPath>${basedir}/versioneye.properties</propertiesPath>
        <organisation>YOUR_ORGANISATION</organisation>
        <team>Owners</team>
      </configuration>
    </plugin>
  </plugins>
</build>

If the plugin can't find the API KEY in any of this locations it will look it up at this place:

~/.m2/versioneye.properties

That means if you don't want to commit your API KEY to the server and share it with your team you can place the file in your home directory and keep it for you. But don't commit this file with secret. So add it to .gitignore exclusions.

Of course you can store the API key in an environment variable VERSIONEYE_API_KEY as well.

export VERSIONEYE_API_KEY=my_secret_api_key

That's a good way to deal with the API key on an CI system.

mvn versioneye:create

If your API KEY is in place you can create a new project at VersionEye based on the dependencies in your pom.xml file with this goal:

mvn versioneye:create

This command will not change your local project. It just sends your dependencies to the VersionEye server and creates, based on that, a new project at www.versioneye.com. If everything went right you will see in the output the URL to your new created VersionEye project. Just copy and paste it into you browser to check it out. Here is an example how it could look like:

Besides that, the plugin will add a project_id to the versioneye.properties file. The project_id is the connection between your pom.xml and the VersionEye project. If the versioneye.properties file doesn't exist yet, it will be created now.

If you don't want that the versioneye maven plugin creates/updates the versioneye.properties file you can skip that step with this line in the plugin configuration:

<updatePropertiesAfterCreate>false</updatePropertiesAfterCreate>

If you do so, you have to add the project_id by hand to the plugin configuration for the next step, the versioneye:update goal.

mvn versioneye:update

After you created a new project on VersionEye you can update it with the dependencies from the pom.xml file with this goal:

mvn versioneye:update

That will simply update the existing VersionEye project with the dependencies from your pom.xml file. It will not change your pom.xml. This goal usually gets executed on a Continuous Integration server after each build.

By the way. If you don't like to have a versioneye.properties file you can set the project_id explicitly in the pom.xml. Just like this:

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <projectId>_YOUR_VERSONEYE_PROJECT_ID_</projectId>
        <organisation>YOUR_ORGANISATION</organisation>
        <team>Owners</team>
      </configuration>
    </plugin>
  </plugins>
</build>

mvn versioneye:licenseCheck

On VersionEye you can have License Whitelists. If you are working with License Whitelists you probably want to break the build if there is a license violation. The next goal will update your VersionEye project with the current dependencies and check them against a License Whitelist. If there is a violation of the License Whitelist this goal will break your build:

mvn versioneye:licenseCheck

mvn versioneye:securityCheck

This goald will check if your dependencies have known security vulnerabilities:

mvn versioneye:securityCheck

If one of project dependencies has a known security vulnerability this goal will break your build!

mvn versioneye:securityAndLicenseCheck

This goald will check if your dependencies have known security vulnerabilities or if they violate the license whitelist on the server:

mvn versioneye:securityAndLicenseCheck

If one of the 2 is violated this goal will break your build!

mvn versioneye:delete

This goal will delete the project from the VersionEye server:

mvn versioneye:delete

This golad will also remove all related versioneye.properties files!

Proxy

Please configure the proxy settings directly in the configuration of the VersionEye Maven Plugin:

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <proxyHost>127.0.0.1</proxyHost>
        <proxyPort>8888</proxyPort>
        <proxyUser>proxy_hopsi</proxyUser>
        <proxyPassword>dont_tell_anybody</proxyPassword>
      </configuration>
    </plugin>
  </plugins>
</build>

If the proxy settings are defined in the pom.xml file the plugin will check these global environment variables:

• VERSIONEYE_PROXY_HOST
• VERSIONEYE_PROXY_PORT
• VERSIONEYE_PROXY_USER
• VERSIONEYE_PROXY_PASSWORD

If you don't want to store the proxy settings in the source code you should use the environment variables above.

Generally a proxy for Maven can be configured in the ${user.home}/.m2/settings.xml) file like described here: https://maven.apache.org/guides/mini/guide-proxies.html.

VersionEye Enterprise

If you are using the VersionEye Enterprise VM in your own private network you probably want to use this plugin against the VersionEye Enterprise API. In that case you can change the baseUrl with this line:

<baseUrl>http://versioneye.my-company.com</baseUrl>

The whole plugin snippet would look similar to this one.

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <baseUrl>http://versioneye.my-company.com</baseUrl>
        <projectId>_YOUR_VERSONEYE_PROJECT_ID_</projectId>
        <organisation>YOUR_ORGANISATION</organisation>
        <team>Owners</team>
      </configuration>
    </plugin>
  </plugins>
</build>

Multi-Module Projects

Assume you have a big Java Enterprise multi-module project with Maven and you want to have all modules monitored by VersionEye. I further assume that all modules have the same parent pom and the modules are listed in the parent pom.xml file. In that case all you have to do is configuring the VersionEye Maven Plugin once in the parent pom.

<build>
  <plugins>
    <plugin>
      <groupId>com.versioneye</groupId>
      <artifactId>versioneye-maven-plugin</artifactId>
      <version>3.11.4</version>
      <configuration>
        <apiKey>MY_SECRET_API_KEY</apiKey>
        <organisation>YOUR_ORGANISATION</organisation>
        <team>Owners</team>
      </configuration>
    </plugin>
  </plugins>
</build>

Now run this command in the parent directory:

mvn versioneye:create

This command will be executed on each module. The plugin will create for each module a new project on VersionEye. Beside that the plugin will create for each module a versioneye.properties file with the corresponding project_id. The file will be created/updated in the src/main/resources directory of each module.

After the projects are created on VersionEye we don't need the create goal anymore. Now we can perform the update goal on each build.

mvn versioneye:update

This will update the project on VersionEye with the current dependencies in the modules pom.xml file. Executing this command in the parent pom directory will update all modules. Ideally this goal is executed on the Continuous Integration System after each build.

Here is a YouTube video which demonstrates how to setup a multi-module project with the VersionEye Maven Plugin.

Configuration Options

The VersionEye Maven Plugin has many configuration options.

      <plugin>
        <groupId>com.versioneye</groupId>
        <artifactId>versioneye-maven-plugin</artifactId>
        <version>3.11.4</version>
        <configuration>
          <projectId>544d0ff9512592562c000003</projectId>
          <!--<apiKey>my_secret_api_key</apiKey>-->
          <!--<baseUrl>http://localhost:3000</baseUrl>-->
          <!--<proxyHost>127.0.0.1</proxyHost>-->
          <!--<proxyPort>8888</proxyPort>-->
          <!--<proxyUser>proxy_hopsi</proxyUser>-->
          <!--<proxyPassword>dont_tell_anybody</proxyPassword>-->
          <!--<updatePropertiesAfterCreate>false</updatePropertiesAfterCreate>-->
          <!--<mergeAfterCreate>false</mergeAfterCreate>-->
          <!--<parentGroupId>com.versioneye</parentGroupId>-->
          <!--<parentArtifactId>versioneye-maven-plugin</parentArtifactId>-->
          <!--<nameStrategy>name</nameStrategy>-->
          <!--<trackPlugins>true</trackPlugins>-->
          <!--<licenseCheckBreakByUnknown>true</licenseCheckBreakByUnknown>-->
          <!--<skipScopes>test,provided</skipScopes>-->
          <!--<organisation>versioneye</organisation>-->
          <!--<team>backend_devs</team>-->
          <!--<name>NameOfTheProjectAtVersionEye</name>-->
          <!--<visibility>public</visibility>-->
          <!--<ignoreDependencyManagement>false</ignoreDependencyManagement>-->
          <!--<transitiveDependencies>false</transitiveDependencies>-->
        </configuration>
      </plugin>
