Gradle For Android: Why Doesn't Javaexec Pick Up My Classpath?

I have an Android project (on Windows) where I am trying to run cucumber-jvm as a non-instrumented 'unit test'. I.e. execute Cucumber features when I run gradlew test. Here are the

Solution 1:

I believe I've found a solution for my issue. Here's the code that works for me:

testOptions {
    unitTests.all {
        def classpath2 = getClasspath()
        javaexec {
            main = "cucumber.api.cli.Main"
            classpath = classpath2
            args = ['--plugin', 'pretty', '--glue', 'gradle.cucumber', 'src/test/java/cucumber/assets']
        }
    }
}

It seems to me that my original call to getClassPath() inside the javaexec closure was returning an empty file collection. At the same time, in the closure for unitTests.all, getClassPath() contains the correct classpath.

By passing the classpath from the external closure into the internal closure via a variable, cucumber.api.cli.Main now runs successfully and my Cucumber features run as part of the Gradle test task.
