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:
