我正在使用Gradle运行Java测试。 以下是我遇到的异常:

事实证明,由于某些原因,我的Gradle使用了JRE的文件夹作为java.home,这就是为什么它找不到tools.jar的原因。我不希望手动将其添加到类路径中。我想知道是否有任何方法告诉Gradle使用JDK的java home而不是JRE的java home?我还尝试在gradle.properties文件中使用org.gradle.java.home进行覆盖,但它没有起作用。非常感谢您的帮助。
当我从我的IDE(IntelliJ IDEA)运行相同的测试时,所有测试都可以成功通过。我在Mac OS上运行所有内容。
println System.getenv("JAVA_HOME")
println System.properties['java.home']
显示:
/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/jre
println System.getenv("JAVA_HOME")
