[2.7-rc-2] Cannot deploy using Maven plugin (No connector available)

Old Forum Archive Bugs
1

I tried updating my project from Gradle 2.4 to Gradle 2.7-rc-2 but I simply can’t get the deployment using the Maven plugin to work.

This is basically how I set it up:

apply plugin: 'maven'

configurations {
    deployerJars // Deployment dependency
}

dependencies {
    deployerJars 'org.apache.maven.wagon:wagon-ftp:2.8'
}

uploadArchives {
    repositories {
        mavenDeployer {
            configuration = configurations.deployerJars

            repository(url: 'ftp://ftp.example.com') {
                authentication(userName: <user>, password: <password>)
            }
        }
    }
}

And this is what I get when executing uploadArchives:

Execution failed for task ':uploadArchives'.
> Could not publish configuration 'archives'
   > Failed to deploy artifacts/metadata: No connector available to access repository remote (ftp://<url>) of type default using the available factories WagonRepositoryConnectorFactory

I think I have seen it fixed somewhere already but it doesn’t seem to be working in 2.7-rc-2. Is there any workaround?

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':uploadArchives'.

This is fixed in the nightlies (which will become 2.8, release will probably be early October).

I see. Considering 2.7 wasn’t released yet, why doesn’t this go into 2.7? I mean it is breaking deploying completely for me and there doesn’t seem to be any workaround. I would love to use the new features in the newer Gradle versions but unfortunately I can’t use all Gradle versions 2.5+ because they’re simply broken.

We plan to release Gradle 2.7 on Monday September 14. This date is important for Buildship, so that Gradle 2.7 can be included in the next major Eclipse service release.

This problem was reported about the time we branched for 2.7, so wasn’t considered during 2.7 release planning. If we were to include the fix now, we’d need to create another release candidate and wait another week, which we don’t want to do.

The target release date for gradle-2.8-rc-1 is Monday September 28 (in 2 weeks). In the meantime you can use the Gradle wrapper to point to a nightly build.
