gradle task jar not working

问题:

I am trying to include a file into my .jar but failed to do so, it says BUILD SUCCESSFUL but the classes.dex is never included inside the jar... I'm really stressed from this graddle stuff... any help is very appreciated, here is my gradle task:

task jar(type: Jar) {
    println( "WHAT" + "${buildDir}\\classes\\classes.dex")
    include "${buildDir}\\classes\\classes.dex"
}

println resolved to existing classes.dex with the correct permission, so I don't see any trouble, I even tried copied out the classes.dex and refer it directly, still it failed.

I use apply plugin 'android-library' though not sure if that is the problem, if I apply plugin 'java' it works...

回答1:

try to change include to from

task jar(type: Jar) {
    println( "WHAT" + "${buildDir}\\classes\\classes.dex")
    from ("${buildDir}\\classes\\classes.dex")
}
