GradleGitHash
A Gradle plugin for creating Java source files that contain the current Git commit hash.
How to use
Add the following to your build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'de.bitdroid.githash:plugin:<GitHash version>'
}
}
apply plugin: 'de.bitdroid.githash' gitHash {
packageName = "<my.fancy.package>"
}
This will add a gitHash task to Gradle which depends on compileJava and listens to changes in the <projectDir>/.git/HEAD file and the <projectDir>/.git/refs/ directrory.
The task will generate a file called GitConstants.java under target/generated-sources/githash/<my.fancy.pacakge> which looks like
package de.bitdroid.githash.example; public final class GitConstants {
public static final String COMMIT_HASH = "70c5a1f5c6fc";
public static final String VERSION = "0.1.2";
private GitConstants() {
}
}
where COMMIT_HASH is the current git commit hash and VERSION and project version set in the gradle build file (if any).
See also the example directory.
Configuration
The default settings for the plugin are as follows:
gitHash {
packageName = "my.package"
outputDir = file('target/generated-sources/githash')
version = project.version
def gitFolder = "${
project.rootProject.projectDir
}
/.git"
gitHeadFile = file(gitFolder + '/HEAD')
gitRefsDir = file(gitFolder + '/refs/')
}
