 Description   

Found on Gradle 2.2.

I'm seeing an org.gradle.api.UncheckedIOException thrown from AbstractFileResolver on Mac OS X 10.9 when I try to run a particular Test task in my project. getCanonicalFile() throws an exception because the submitted class path is too long.

Seems to be coming from this optimization in AbstractFileResolver:

// Short-circuit the slower lookup method by using the canonical file
File canonical = candidate.getCanonicalFile();
if (candidate.getPath().equalsIgnoreCase(canonical.getPath())) {
return canonical;
}

I was able to work around the issue by enclosing the block above in a try-catch, so AbstractFileResolver.normalize() proceeds with the 'slower' lookup in the case of an IOException here.

Would recommend including something along those lines in the next release in case anyone else runs into this issue.

Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task [task name removed]

This is reproducable via:


buildscript {
    repositories {
      mavenCentral()
    }

    dependencies {
      classpath "commons-lang:commons-lang:2.6"
    }
}

def fileName =  org.apache.commons.lang.RandomStringUtils.randomAlphanumeric(260) + ".txt"

task generate << {
    file("build/$fileName").text = "blubb"
}

task myCopy(type:Copy) {
  dependsOn generate
  from files("build/$fileName")
  into "build/targetDir"
}

As announced on the Gradle blog we are planning to completely migrate issues from JIRA to GitHub.

We intend to prioritize issues that are actionable and impactful while working more closely with the community. Many of our JIRA issues are inactionable or irrelevant. We would like to request your help to ensure we can appropriately prioritize JIRA issues you’ve contributed to.

Please confirm that you still advocate for your JIRA issue before December 10th, 2016 by:

  • Checking that your issues contain requisite context, impact, behaviors, and examples as described in our published guidelines.
  • Leave a comment on the JIRA issue or open a new GitHub issue confirming that the above is complete.

We look forward to collaborating with you more closely on GitHub. Thank you for your contribution to Gradle!
