I get a NPE when checking for dependency updates, and I can't seem to find the reason in the debug/stacktrace log.

Can you please provide your Gradle build file? Or can you even track down the specific dependency that causes the issue?

@jochenberger

Also, does gradle --info dependencyUpdates provide any helpful information?

@henrik242

Here's the full build log with --info enabled: https://www.dropbox.com/s/a3ail1o3adbdshv/gradle-version-plugin.txt (87MB)

Thanks. You accidentally also enabled --debug.
First of all, I think we need more logging, it's quite hard to determine at which dependency the task actually fails.

@henrik242

Author

I added --debug since I thought you'd want all available info :)

If there's any more information I can provide, please tell.

I'm about to add some logging to the task execution. Would you be able to compile the plug-in from source for testing purposes?

@henrik242

Author

Sure.

@jochenberger

Great, thanks. I just committed a change that adds more logging. Could you please retry with that version and supply the output of gradle --info --stacktrace dependencyUpdates?

So, the dependency that causes the problem is libthrift. Could you please paste the respective dependency declaration from your build.gradle?

@henrik242

ext.versions = [
    ...
    thrift: '0.6.1',
    ...
]
ext.libs = [
    ...
    thrift: dependencies.create("org.apache.thrift:libthrift") {
        exclude group: "javax.servlet"
        exclude group: "junit"
    },
    ....
]
subprojects { innerProject ->
    ....
    configurations {
        all*.resolutionStrategy {
            force "org.apache.thrift:libthrift:${versions.thrift}"
            ....
        }
    ....
    }
}

@jochenberger

The version ends up as null (grep for libthrift in the log). I'm not sure why though. Could you add a println in your build script to see if it's also null there?

@henrik242
Copy link
Author

A println "VERSION: ${versions.thrift}" within all*.resolutionStrategy yields VERSION: 0.6.1

@henrik242
Copy link
Author

The problem disappears if I replace thrift: dependencies.create("org.apache.thrift:libthrift") with thrift: dependencies.create("org.apache.thrift:libthrift:${versions.thrift}")

@jochenberger

Collaborator

That's what I expected. So we're probably missing that version override. That's probably going to take me a while.

Not a problem since I have a workaround now. Thanks for the swift replies!

The NPE should be fixed. I've created a new issue for the remaining problem.
