I have a Java project and this task:  
If I run this task twice it will be up-to-date the second time. This is all god.  
Now if a change my Java code then the classes task is NOT up-to-date. So the code i compiled. So far so good.

The problem is that my task convertEgl2Cobol is still up-to-date. But how can this be?? The tasks it depends on is NOT up-to-date so this should not be up-to-date either.  
The inputs and outputs does change in this case.

Can someone help me understand why this incremental build does not work the way I think it should.

Im using Gradlew 3.2 on Windows 7.

```
task convertEgl2Cobol(dependsOn: classes) {
    description 'Converts EGL to Cobol.'
    group 'convert'

    doLast{
        MODEL_LIST.split(',').each{ model ->
            javaexec {
                classpath = sourceSets.main.runtimeClasspath
                main = 'dk.xact.translate.TranslateXactSample'
                args model.trim()
                jvmArgs = ['-Dfile.encoding=UTF-8', '-Xms8g', '-Xmx16g']
            }
        }
    }

    inputs.dir fileTree(dir: EGL_SOURCE_DIR, include: '**/*.egl')
    outputs.dir OUTPUT_PATH + '/generated'

    doFirst {
        delete OUTPUT_PATH + '/generated'
    }
}
```

Up-to-date checking does not take into account any task dependencies. Your conversion task needs to specify that the outputs of the classes task are inputs.

Thank you for clarifying that.  
That actually make sense.
