java - Want to specify jar name and version both in build.gradle

Question

I want to specify the jar name and version in build.gradle, so my build.gradle looks like below.

apply plugin: 'java'

version = "1.00.00"

 dependencies { 
     compile files('../../lib/abc.jar') 
} 

jar{
    manifest{
        attributes ("Fw-Version" : "2.50.00", "${parent.manifestSectionName}")

    }
    archiveName 'abc.jar'
}

So when I do

gradle clean build, what I was expecting was that the generated jar name would be abc-1.00.00.jar

But its not happening, the output jar name is getting as abc.jar only and its just ignoring the version. I want to specify both jar name and version, so how can I achieve that?

Answer 1

archiveName 'abc.jar' in your jar configuration is forcing the name to be 'abc.jar'. The default format for the jar name is ${baseName}-${appendix}-${version}-${classifier}.${extension}, where baseName is the name of your project and version is the version of the project. If you remove the archiveName line in your configuration you'll have the format you're after. If you want the name of the archive to be different from the project name set the baseName instead, e.g.

jar {
    manifest{
        attributes ("Fw-Version" : "2.50.00", "${parent.manifestSectionName}")
    }
    baseName 'abc'
}

See https://docs.gradle.org/current/dsl/org.gradle.api.tasks.bundling.Jar.html#org.gradle.api.tasks.bundling.Jar:archiveName for more info on configuring the jar task.
