Gradle: Cant exclude one of two log4j dependencies?

Occuring error

While trying to build an android studio project with gradle i recieve this error:

Execution failed for task ':app:transformResourcesWithMergeJavaResForPlainDebug'.
com.android.build.api.transform.TransformException:
com.android.builder.packaging.DuplicateFileException:
Duplicate files copied in APK org/apache/log4j/lf5/config/defaultconfig.properties

File1: ...\app\libs\tn5250j.jar
File2: ...\app\build\intermediates\exploded-aar\xxx\xxx\jars\libs\log4j-1.2.17.jar

In two included .jars the library log4j is used. I must include both libs to my android application. One of them is an .aar file, the other is a .jar.

Gradle settings

Dependencies from my build.gradle:

dependencies {
    debugCompile 'xxx@aar'
    releaseCompile 'xxx@aar'
    
    compile files('libs/commons-net-3.5.jar')
    compile files('libs/jackson-core-2.8.1.jar')
    compile files('libs/jackson-databind-2.8.1.jar')
    compile files('libs/jackson-annotations-2.8.1.jar')
    compile files('libs/tn5250j.jar')
}

Packaging options from my build.gradle:

packagingOptions {
    exclude 'main/AndroidManifest.xml'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/LICENSE'
}

I have no idea what tn5250j.jar is but it looks like it's an UBER jar which is packing log4j inside. You could either exclude the log4j dependency from your build (since it's packed inside tn5250j.jar) or you tweak tn5250j.jar to remove log4jand use the "tweaked" jar instead. Eg:

dependencies {
    ...
    compile files("$buildDir/tweaked/tn5250j-tweaked.jar")
}
task tweakTn5250j(type: Zip) {
    from zipTree('libs/tn5250j.jar').matching {
        exclude 'org/apache/log4j/**'
    }
    destinationDir = "$buildDir/tweaked"
    archiveName = 'tn5250j-tweaked.jar'
}
classes.dependsOn tweakTn5250j
