如何在 Gradle 中创建两个任务

Question

I have a Java project with Gradle as build system.
I need to create two one-purpose build tasks , but with different versions of jar file.
Specifically, i need:

• for build task in local machine use -LOCAL version for .jar (for example projectName-LOCAL.jar )

• for build task in GitLab CI\\CD system use numbered version ( projectName-1.1.1.jar )

The version for GitLab CI\\CD taken from commit tag, from GitLab predefined ENV variables.

So, i have a default build.gradle file, where:

group = 'projectName'
version = 'LOCAL'
sourceCompatibility = '11'

jar {
    manifest {
        attributes "Main-Class": "projectName.Application"
    }
    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

This task must run on local machine and create projectName-LOCAL.jar . What he's doing is.
How can I implement this in another task with numbered version especially for GitLab CI\\CD?

Answer 1

Gradle by default names jar files as ${baseName}-${appendix}-${version}-${classifier}.${extension} .

So you can simply change version depending on a condition.

Something like this should work:

ext {
    isLocal = System.getenv('ENV') == 'LOCAL'
}

jar {
    if (isLocal) version = 'LOCAL'
}

For working with local, you can use ENV=LOCAL ./gradlew jar and use your normal commands without the ENV part for GitLab.
