Getting File permissions error when exploding the cucumber-jvm.jar

Question

I am trying to create an executable jar for functional tests by exploding the dependency jars, using gradle task of type Jar.

Cucumber-1.1.3 is one of the dependencies. I am using gradle 1.1 with JVM 1.6 (company standards)

I get the following error :

org.gradle.api.GradleException: Could not expand ZIP '/dev/shm/263985/transformer/caches/artifacts-14/filestore/info.cukes/cucumber-java/1.1.3/jar/4b389fbe494942b319518d27ae38571f477967f6/cucumber-java-1.1.3.jar'. at

Note: This works fine when you use gradle 1.1 with JVM 1.7.

Let me know if you guys know why this is happening and is there any fix or alternatives. Thanks in advance!!

Answer 1

You may be encountering an issue we've run into. I'm not sure we 100% understand it, but it appears that when unzipping an archive that has read-only files in it gradle can struggle. Gradle attempts to check the zip against any files it has already unzipped in order to know if the unzipping task is up-to-date, and this process can blow up if the archive has read-only files.

Notice lines like this in your stacktrace:

org.gradle.api.internal.changedetection.CompositeUpToDateRule.create
Caused by: java.io.IOException: Failed to set file permissions 420 on file

Not quite a smoking gun, but a pretty strong implication. Our solution (hacky, I'll admit) was to use the following code:

def fixExpandedArchivesForLinux() {
    // This interesting hackery fixes the expandedArchives directory
    // to avoid the read-only extracted ZIP file contents issue.
    def dir = new File(buildDir, "tmp/expandedArchives")
    FilePermissions.chmodRecursively(dir, 0200)
}

You can put that in a do first to allow gradle to re-expand the archive while it checks the up-to-date status.

Answer 2

I got a similar issue when working with android libraries (aars). I got it working by deleting the directories where the aars are exploded.

def str = "rm -rf "+buildDir.absolutePath+"/exploded-aar" str.execute()

Answer 3

I just had the same problem involving a file called "??.class" in cucumber. The exception cause from a run of

./gradlew connectedCheck --debug --stacktrace

showed the following root cause

Caused by: net.rubygrapefruit.platform.NativeException:
Could not set UNIX mode on .../app/build/tmp/expandedArchives/cucumber-java-1.2.4.jar_bkzp93af0tagkjvsr5vkgywjd/cucumber/api/java/ar/??.class:
could not convert string to current locale

It turns out that I had a problem with my locale for which I had previously ignored all warnings from other command line tools. I checked which locales are mentioned in /etc/locale.conf, uncommented the corresponding lines in /etc/locale.gen and ran

sudo locale-gen

to regenerate the locales. After this, the file names showed up like ਅਤੇ.class and the unzipping worked flawlessly.
