How to get gradle to output dependency hash for each dependency

问题

I am seeing, for the first time in my life, a situation where

gradle compileJava check runs fine locally but when I try to run the same commands with bitbucket pipelines I get NoSuchClassDefError

I do gradle user-login-server:dependencies locally and on pipelines and the versions for the artifacts I suspect are identical

So the only explanation I can come up with is that the actual artifacts are different.

Hence: How can I force gradle to output the hash of every dependency so I can trackdown what's going wrong?

回答1:

You could loop across the jars and print out a hash like so.

task printDependencyHashes() {
    def hash = { File file ->
        def md = java.security.MessageDigest.getInstance('MD5')
        file.eachByte(1024 * 4) { buffer, len ->
            md.update(buffer, 0, len)
        }
        return md.digest().encodeHex().toString()
    }

    doLast {
        configurations.compileClasspath.each { println "${it.name}: ${hash(it)}" }
    }
}
