NullPointerException in main thread. #10

I have successfully built and generated the jar file from the source in a docker container. But when I run it with

java -jar build/libs/droidmate-2-2.0.0-all.jar --Output-outputDir=/tmp_out --Selectors-actionLimit=200

I got this exception.

Can you try running

./gradlew run --args="--Output-outputDir=/tmp_out --Selectors-actionLimit=200"

to see if the same error appears?

michael172849 commented 4 years ago

I got the same error.

natanieljr commented 4 years ago

I pushed a change to master.

The problem appears to be that DM is looking for the filename of the parent directory to the output.

Since the directory is / it doesn't have a filename.

Plase have a look at the master branch and see if it works for you.

Assuming everything is working since there was no feedback after the solution
