java.lang.VerifyError with upload to WebDAV repository

[JurgenLust]

Hi,

I'm trying to upload an artifact to a Maven repository, using WebDAV. I'm using wagon-webdav-1.0-beta-2.

The uploadArtifacts section of my build file looks like this:

uploadArchives {
    repositories.mavenDeployer {
        name = 'googleCodeDeployer'
        configuration = configurations.mavenDeploy
        repository(url: "dav:https://bzb-framework.googlecode.com/svn/maven-repository/") {
        authentication(userName: "my.name", password: "mypassword")
        }
    }
}

Now, when I run 'gradle upload -s', I get the following stacktrace:

org.gradle.api.GradleScriptException: Build file '/Users/jlust/Projecten/BeeWorks/meiji-framework/trunk/gradle/hibernate-tools/build.gradle'

Any idea where to look for a solution?

Hi,

I will have a look into this, to see if I can reproduce it. It might
take a day or two.

Hi,

This looks like a jar versioning problem. Could you try replacing
$gradleHome/lib/commons-httpclient-3.0.jar with
commons-httpclient-2.0.2.jar, and removing
$gradleHome/lib/webdavlib-2.0.jar, and see if it works.

I will keep digging to see if there's a better workaround.

Could you also add a JIRA issue for this?
