New sourceSet by gradle cannot be seen in Eclipse - eclipse

Question

I have created additional source set called "integration-test" in my gradle project. Ewerything works fine, but eclipse cannot see dependency classes defined exactly for this source set.
subprojects {
apply plugin: 'java'
apply plugin: 'eclipse'
repositories {
mavenCentral()
}
sourceSets {
integrationTest {
java {
compileClasspath += main.output + test.output
runtimeClasspath += main.output + test.output
srcDir file('src/integration-test/java')
}
resources.srcDir file('src/integration-test/resources')
}
}
configurations {
integrationTestCompile.extendsFrom testCompile
integrationTestRuntime.extendsFrom testRuntime
}
dependencies {
testCompile 'junit:junit:4.12'
testCompile 'org.mockito:mockito-all:1.10.19'
integrationTestCompile 'org.springframework:spring-test:4.1.7.RELEASE'
compile 'org.springframework:spring-context:4.1.7.RELEASE'
compile 'org.springframework:spring-core:4.1.7.RELEASE'
}
task integrationTest(type: Test) {
testClassesDir = sourceSets.integrationTest.output.classesDir
classpath = sourceSets.integrationTest.runtimeClasspath
outputs.upToDateWhen { false }
}
check.dependsOn integrationTest
integrationTest.mustRunAfter test
version = '1.0'
}
When i build this project by command "build gradle", project is build, the only problem is with eclipse. If I change dependency 'org.springframework:spring-test:4.1.7.RELEASE' from "integrationTestCompile" to "testCompile", problem is gone.

Answer 1

It is a little late to answer your question, but I just found a solution to this, since I had the exact same problem.
Adding this:
eclipse {
classpath {
plusConfigurations.add configurations.integrationTestCompile
plusConfigurations.add configurations.integrationTestRuntime
}
}
to the gradle file solved the problem. I hope it does the same for you.

Answer 2

An approach that I found that worked really well for me is this test sets plugin: https://plugins.gradle.org/plugin/org.unbroken-dome.test-sets
It made it really easy to add integration tests to my module. And it works with the eclipse plugin automatically.
