Compilation using custom source set produces org.gradle.api.UncheckedIOException


(jason.interlichia) #1

Problem description: As described below, I am trying to compile all of the source code in foo.bar.baz, but I get the exception trace below. It depends on some common code which is at the same level under the Eclipse project’s top level. If I move the common code one directory down from the top, then it compiles. This doesn’t make sense. I really need it to work with it common code at the same level. I have tried running the compileJava task both from the command line and from the Gradle UI. Thanks in advance for anyone who can help.

Environment: -Eclipse 4.2 Juno -Tried with both Gradle 1.5 and Gradle 1.6 -Windows 7 -JDK 1.7

Eclipse setup:

Under the Eclipse project top level folder C:/eclipse_workspace/sample_project/, the setup is as follows:

a) Top level build.gradle file at top level b) Java source code to compile is in package foo.bar.baz which is directly under Eclipse project’s top level

c) build.gradle file in foo/bar/baz d) common code classes that foo.bar.baz code depends on are in common/src/code under Eclipse project’s top level

foo/bar/baz/build.gradle snippet for custom source set that does NOT compile and produces the org.gradle.api.UncheckedIOException stack trace below:

sourceSets {
         main {
 compileClasspath = compileClasspath + files("C:/eclipse_workspace/sample_project/")
        java {
            srcDirs = [rootProject.projectDir.path + "/foo/bar/baz"]
                  }
       }
}

foo/bar/baz/build.gradle snippet for custom source set that DOES compile by moving the common/src/code to common2/common/src/code

sourceSets {
         main {
 compileClasspath = compileClasspath + files("C:/eclipse_workspace/sample_project/common2")
        java {
            srcDirs = [rootProject.projectDir.path + "/foo/bar/baz"]
                  }
       }
}

Exception stack trace:

  • What went wrong: Build aborted because of an unexpected internal error. Please file an issue at: http://forums.gradle.org.

  • Try: Run with --debug option to get additional debug info.

  • Exception is:

org.gradle.api.UncheckedIOException: java.io.IOException: The process cannot access the file because another process has locked a portion of the file
