JarCastinggradle-build-info-plugin
Gradle plugin to include build information such as Git commit ID to your JAR.
Usage
Apply plugin:
plugins {
id 'com.github.ksoichiro.build.info' version '0.2.0'
}
Note that you can use this plugin only when you use java plugin because you build JAR:
apply plugin: 'java'
When used with Spring Boot Actuator dependency, this plugin will also generate git.properties, which will be recognized by Spring Boot Actuator's info endpoint.
Then just build your project:
$ ./gradlew build
Now your Manifest in JAR includes special attributes:
$ unzip -p build/libs/yourJar.jar META-INF/Manifest.MF
Manifest-Version: 1.0
Git-Branch: master
Git-Commit: 154f026
Git-Committer-Date: 2015-12-17 20:05:55 +0900
Build-Date: 2015-12-17 20:15:15 +0900
Build-Java-Version: 1.8.0_45
Build-Java-Vendor: Oracle Corporation
Build-Os-Name: Mac OS X
Build-Os-Version: 10.10.1
And when Spring Boot Actuator is used with it, git.properties will be generated:
$ cat build/resources/main/git.properties
git.branch=master
git.commit.id=38a0c0c
git.commit.time=2015-12-16 23\:40\:13 +0900
Configuration
You can configure this plugin with buildInfo extension in build.gradle:
buildInfo {
// Date format string used to Git committer date.
committerDateFormat 'yyyy-MM-dd HH:mm:ss Z'
// Date format string used to build date.
buildDateFormat 'yyyy-MM-dd HH:mm:ss Z'
// Set to true if you want to generate/merge Manifest.MF.
manifestEnabled true
// Set to true if you want to generate git.properties.
// Default is false, but when you use Spring Boot Actuator
// and you don't set this property explicitly to false,
// git.properties will be generated.
gitPropertiesEnabled false
// Behavior when the plugin cannot read .git directory.
// Set to MODE_IGNORE if you want to ignore it and proceed task.
// Set to MODE_ERROR if you want to throw an exception to stop build.
// Default is MODE_DEFAULT.
// MODE_DEFAULT will set the values of branch, commit,
// and committer date to "unknown", then proceed task.
gitInfoMode com.github.ksoichiro.build.info.BuildInfoExtension.MODE_DEFAULT
// Set to false if you want to suppress log when .git directory
// cannot be read.
// Default is true.
warnIfGitDirectoryIsMissing false
// Set to false if you want to exclude some attributes
// from the manifest file.
// All properties are true by default.
attributeGitBranchEnabled false
attributeGitCommitEnabled false
attributeGitCommitterDateEnabled false
attributeBuildDateEnabled false
attributeBuildJavaVersionEnabled false
attributeBuildJavaVendorEnabled false
attributeBuildOsNameEnabled false
attributeBuildOsVersionEnabled false
}
