Error running customDistribution sample code

Neil1 · October 22, 2012, 4:24pm

I ran the ‘dist’ task on the customDistribution sample as follows:

<gradle_dir>\samples\customDistribution\plugin> gradle dist -Dhttp.proxyHost=<host> -Dhttp.proxyPort=<port>

The output was:

Sounds like you might have multiple Gradle daemons running. Try ‘gradle --stop’. Also note that you must do a clean build whenever you switch Gradle versions.

Neil1 · October 22, 2012, 4:47pm

I tried ‘gradle --stop’ and then reran the ‘dist’ task - same error.

I also tried deleting my ‘%USERPROFILE%/.gradle/daemon’ directory because I’ve had a problem with dead daemons before - no difference.

I tried ‘clean’ as well, even though it shouldn’t have been necessary because I haven’t changed the gradle version specified in the build script.

Peter_Niederwieser · October 22, 2012, 10:20pm

Can you try without the daemon? Do you have a tool to check which process keeps the file locked? ‘gradle dist’ works just fine for me (with daemon).

Neil1 · October 23, 2012, 8:49am

I tried running

<gradle_dir>\samples\customDistribution\plugin> gradle --no-daemon dist -Dhttp.proxyHost=<host> -Dhttp.proxyPort=<port>

and found the same problem. (I also ran ‘gradle --stop’ prior to this.) The same error occurred - “org.gradle.api.UncheckedIOException: java.io.IOException: The process cannot access the file because another process has locked a portion of the file”.

I’ll be happy to check which process is keeping the file locked, but I don’t know which file. I would assume that it’s a zip file that I should be looking for, but here’s the output of ‘tree /F’ after invoking the above command:

Turn on debug log with ‘-d’, and stack trace with ‘-s’. Maybe that gives a hint. Also run ‘jps’ and make sure that there are no other Gradle daemons running. Reboot may also help.

Neil1 · October 23, 2012, 9:38am

Ok, I found the problem. I noticed that the build script was copying from ‘gradle.gradleHomeDir’ which in my case was ‘C:\Tools\gradle-1.2’. However, the location of the sample project (and the output zip) was a subfolder of this, resulting in an attempt to recursively zip, or running into a file-lock problem.

(If memory serves me correctly I also ran into a similar issue when creating a zip without explicitly excluding the zip from the zipping task, if that makes sense. The task would run indefinitely, resulting in a zip file gigabytes in size. But that’s a separate issue.)

My workaround was to move the ‘samples’ directory outside of my ‘gradle-1.2’ directory.

I have been using your Standard Distribution from http://services.gradle.org/distributions/gradle-1.2-all.zip which puts the ‘samples’ directory inside ‘gradle-1.2’.

I don’t know if my workaround is the most appropriate solution, but I would have thought better error reporting would be worthwhile. And possibly change the structure of your Standard Distribution.
