The build fails, because dexterous is not only a library used in android apps, it's also a desktop standalone tool (See file: desktop.gradle).

You use android's Log classes in dexterous/src/main/java/comm/android/dx/merge/MethodFilter.java. Please switch to the Logger :https://github.com/Project-ARTist/dexterous/blob/master/src/main/java/saarland/cispa/utils/LogA.java
