Hi, I am new to gradle projects. My task when run, can’t find the junit related classes nor the main method. I want to use the junit that is bundled as a jar in the lib folder. I have a project structure like this -

```gradle
test
    ------lib
            ------junit-4.4.jar(with other jar files)
    ------code.jar

```

Here is my code -

```gradle
apply plugin: 'java'
  repositories {
 flatDir{
    dirs 'D:/test/lib'
 }
}
  dependencies {
   compile group: 'junit', name: 'junit', version: '4.4'
   }
     task runTest(type:JavaExec){
   main = 'com.org.mainMethod'
 classpath = files([repositories.flatDir,'D:/test/code.jar','D:/test/lib'])
}

```

The task fails because it cannot find the junit related files. I am completely lost now -

```gradle
java.lang.NoClassDefFoundError: org/junit/runner/notification/RunListener
Caused by: java.lang.ClassNotFoundException: org.junit.runner.notification.RunListener
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class:com.org.mainMethod
Program will exit.

```

Any help is appreciated.

‘flatDir’ dependencies don’t need a ‘group’, although it may not be a problem to declare one. Try to omit the group or use the shorthand notation (‘compile “:junit:4.4”’). The ‘classpath’ configuration for the ‘runTest’ task is incorrect (you can’t put a repository or a directory on a Java class path). If these are JUnit tests, you should probably use the ‘test’ task provided by the ‘java’ plugin instead.

Thanks for the reply Peter. The biggest issue was that the jar files under the d:/test/lib were not getting included. After adding a dependency to include all jar files, the problem got resolved.

Also fixed the classpath as suggested 🙂

```gradle
javaRun fileTree(dir: 'D:/test/lib', include: '*.jar')

```
