通过Jenkins在Android Gradle中设置构建属性

Question

How do you tell Jenkins to set a property inside gradle.properties in an Android project? I've figured out how to get the properties from Gradle into Jenkins (by using the EnvInject plugin and simply entering gradle.properties into the property file field) but I also want the build number that is managed by Jenkins to be injected into the build artifact.

I also want to set the filename of the resulting artifact which, I think, needs to be injected by using archivesBaseName . But that property isn't part of gradle.properties so I wonder how do I access it?

So far I've only found solutions that change the build.gradle file (or other gradle scripts) in the Android project itself. But that's not what I want to do because that would make the Android code base rely on Jenkins.

Instead I want Jenkins to provide the build number and artifact file name to the Android project before it compiles the code.

The server runs on a Mac. Does anyone have a solution for this? Any shell/Groovy script that does the job would be welcome.

We are just wrinting a file version.properties, which is generated by jenkins "echo "VERSION_CODE=${BUILD_NUBMER}" > version.properies" script.

Then gradle script imports it as following:

// Version code is loaded from a properties file
        def versionPropsFile = file('version.properties')
        if (versionPropsFile.canRead()) {
            def Properties versionProps = new Properties()
            versionProps.load(new FileInputStream(versionPropsFile))

            def code = versionProps['VERSION_CODE'].toInteger()

            versionCode code
        }
        else {
            throw new GradleException("Could not read version.properties!")
        }

        buildConfigField "String", " some _VERSION", "\"${getVersionString()}\""
    }
