Hi There,
I'm observing a werid behavior in the Maven Plugin. It seems as if it's uploading certain artifacts multiple times. So either I'm doing something wrong (which might very well be 
) or this might be a bug.
I have a basic jar project, of which I want to deploy 4 artifacts:
- The main library jar
- The sources of the main library jar
- A jar containing thecompiled test classes
- The sources of the test classes
I want the sources jars to just use classifiers. The test jars should get their own artifactIds.
Here are the relevant parts of my build.gradle:
task sourcesJar(type: Jar)
{ from sourceSets.main.allSource classifier = 'sources' }task testJar(type: Jar)
{ baseName = project.name + '-tests' from sourceSets.test.output }task testSourcesJar(type: Jar)
{ baseName = project.name + '-tests' classifier = 'sources' from sourceSets.test.allSource }artifacts
{ archives sourcesJar, testJar, testSourcesJar }uploadArchives {
def mvnUser = 'user'
def mvnPassword = 'pwd'
repositories.mavenDeployer {
configuration = configurations.mavenDeployer
uniqueVersion = false
def mainPom = addFilter('main')
{artifact, file -> !artifact.name.endsWith("-tests") }def testsPom = addFilter('tests')
{artifact, file -> artifact.name.endsWith("-tests") }def poms = [ mainPom, testsPom ]
poms.each
{ it.version = project.version }repository(url: "http://myrepo") {
authentication(userName: "${mvnUser}", password: "${mvnPassword}")
}
snapshotRepository(url: "http://myrepo-snapshots") {
authentication(userName: "${mvnUser}", password: "${mvnPassword}")
}
}
}
When I run uploadArchives with --info, I get the following output:
> :mylib:uploadArchives
Task ':mylib:uploadArchives' has not declared any outputs, assuming that it is out-of-date.

[ant:null] An error has occurred while processing the Maven artifact tasks.
Diagnosis:
Error deploying artifact 'mygroup:mylib-tests:jar': Error deploying artifact: Failed to transfer file: [8]http://myrepo/mygroup/mylib-tests/4.0.... Return code is: 400
The HTTP 400 is our repo's way of indicating the artifact alreacy exists and cannot be overwritten in a release repository. This behavior seems corrent as it looks like gradle is trying to upload the same artifact (mylib-tests-4.0.0-sources.jar) twice.
I have added this code to get the list of artifacts:
configurations.archives.artifacts.each { println "ARTIFACT: ${it}" }
And I got the output:
ARTIFACT: ArchivePublishArtifact mylib:jar:jar:
ARTIFACT: ArchivePublishArtifact_Decorated mylib:jar:jar:sources
ARTIFACT: ArchivePublishArtifact_Decorated mylib-tests:jar:jar:
ARTIFACT: ArchivePublishArtifact_Decorated mylib-tests:jar:jar:sources
Which looks correct to me...
Any clue what might be wrong here?
Many thanks in advance,
Mike
