How to use spoon to compile Hadoop projects

Question

I am a new user of Spoon and Astor. Recently I am using Astor(SpoonLabs/astor) to do some automated bug repair work.

The Astor will firstly use Spoon library to compile and analyze the project source code. Now I can use Spoon to synthesize small projects successfully, but it cannot successfully compile Hadoop submodule (e.g. hadoop/hadoop-common-project/hadoop-auth).

I found Spoon has problems in compiling the model. Seems that Spoon can NOT get the declared type from package-info.java file. Is there anyone knowing how to fix this issue? Thanks a lot!

the log information is listed below:

I don't think stackoverflow is the right place for your problem here: it's either a bug in Spoon or in Astor. I suggest you to open the issue in Astor (https://github.com/SpoonLabs/astor/issues) first and we'll see if it's related to Astor or Spoon. If you can, when you'll create the issue provide the full command line argument you used with Astor so I'll be able to replicate easily your bug.
