Archiving signing does not occur, always "task is up-to date"

I’ve been struggling with the following challenge:

My top level project (Tapestry) uploads aggregate source and JavaDoc ZIP archives as part of a generateRelease build.

Now, with Luke’s help in the class, I got the .md5 checksums for each archive file generated and uploaded along with the archive itself.

The next challenge is the signing of the archives with PGP.

configurations {
     archives
    uploads.extendsFrom archives, signatures
  }
      task generateMD5Checksums(type: GenMD5) {
    group "Release artifact"
    description "Creates MD5 checksums for archives of source and JavaDoc"
    source configurations.archives
    outputDir "$buildDir/md5"
  }
    dependencies {
     archives files(zippedJavadoc, zippedSources)
    uploads files(generateMD5Checksums)
  }
    signing {
     sign configurations.archives
  }
    task uploadSourcesAndJavadocs(type: Scp) {
    group "Release artifact"
    description "Uploads source and JavaDoc Zips and MD5 checksums and PGP signatures to people.apache.org"
      dependsOn signArchives
      source files(configurations.uploads)
    host "people.apache.org"
    userName deployUsername()
    password deployPassword()
    // The destination folder needs to already exist.
    destination "public_html/tapestry-releases"
    verbose true
      doFirst {
       logger.info "Uploads files: ${source.files}"
    }
  }

This works for the archives and the .md5s, but not the .asc (PGP key signatures) which don’t even get generated:

I wish there was a way, short of --debug, to squeeze more information out of the build about task interdependencies.

Is there some hidden dependency between the “java” plugin and the “signing” plugin? Signing appears to work correctly for the signing of artifacts uploaded to the Nexus repository.

The problem is this:

dependencies {
     archives files(zippedJavadoc, zippedSources)
    uploads files(generateMD5Checksums)
  }

You’re adding these things as dependencies instead of artifacts. A ‘Confifguration’ models both incoming (dependencies) and outgoing (artifacts).

The signing plugin operates on artifacts, not dependencies.

The simplest solution would be this (including removing the dependency block I copied above):

artifacts {
  archives zippedJavadoc, zippedSources
}
configurations {
  upload.extendsFrom archives, signatures
}
…
task uploadSourcesAndJavadocs(type: Scp) {
  …
  source generateMD5Checksums, configurations.upload.allArtifacts.files
  …
}

This confusion around configurations modelling both incoming and outgoing is a known quirk.

Wow, I definitely missed that distinction.

Also, it appears to be:

source files(generateMD5Checksums, configurations.upload.allArtifacts.files)

Thanks for the help!
