packageTemplate task issue

[saturov]

For some reason I can't zip template directory. I ran task ./gradlew packageTemplateTest and building started, but in 3-4 seconds it failed with the following message:

FAILURE: Build failed with an exception.

* What went wrong:
Ambiguous method overloading for method java.io.File#<init>.
Cannot resolve which method to invoke for [null, class java.lang.String] due to overlapping prototypes between:
    [class java.lang.String, class java.lang.String]
    [class java.io.File, class java.lang.String]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 3.74 secs

What am I doing wrong?

Thanks.

Can you please run ./gradlew --stacktrace packageTemplateTest? It would be useful to know where the exception is being thrown from.

Also, which version of the Lazybones Gradle plugin are you using?

[saturov]

I'm using this version: classpath "uk.co.cacoethes:lazybones-gradle:1.2.4".

You can see stacktrace below:

* Exception is:

BUILD FAILED

Another strange thing is that ./gradlew packageAllTemplates goes successful, but no zip archive is created. I ran this task with --debug suffix and saw the following line:

11:01:18.525 [INFO] [org.gradle.api.internal.tasks.execution.SkipTaskWithNoActionsExecuter] Skipping task ':packageAllTemplates' as it has no actions.

I don't know, if this connected with the first issue.

[saturov]

Hm, I'm trying to build template for Android project and I have the following block of dependencies in my build.gradle file:

dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath "uk.co.cacoethes:lazybones-gradle:1.2.4"
}

This may cause this issue... But without first gradle dependency nothing is working in my template application.

[pledbrook]

It's a bug, but also an issue with naming. The plugin is looking for a directory called template-test that contains your template source. The reason that packageAllTemplates does nothing is that the plugin can't find any templates to package up.

By default, the directory containing the source templates is /templates. By the sounds of it, that's empty.

[pledbrook]

With regard to your last comment, why are you including the Android tools? I can understand putting that declaration in the template build file (which gets packaged up), but is it necessary for the template project itself? I can't imagine it causing any problems for the Lazybones plugin, though.

[saturov]

I had problems with understanding of necessary directory structure for templates till I try "lazybones create lazybones-project my-lzb-templates". I can't find no information about it before in wiki, cause there said just: "Create the directory structure and files for the template". Now it's rather clear, thank you.

[pledbrook]

You're right, there's no mention of what the conventions are for the plugin. I'll leave this issue open as both a documentation enhancement (explain the build conventions) and a bug.
