Wie analysing guava I had similar problems:

git clone https://github.com/google/guava.git

cd guava

mvn dependency:copy-dependencies -DoutputDirectory=dependencies -DoverWriteSnapshots=true -DoverWriteReleases=false``

../jdt2famix/release/jdt2famix.sh 

Then I got the following exception:

jdt2famix - parsing started - /Users/meinert/Develop/moose_parser/guava

As a first test I tried to import the spring framework from github (https://github.com/spring-projects/spring-framework) and got some exceptions e.g when I tried to import spring-core:

jdt2famix - importing - /Users/meinert/Develop/moose_parser/spring-framework/spring-core/src/main/java/org/springframework/util/SocketUtils.java

improve the error handling. As Java has a ton of edge cases, it would be great if you would use it to parse your systems and report possible errors. We would then manufacture test cases out of those.



I'll definitely give it a try. Because the number of people who'll try this out will be limited, to be sure that there aren't any bugs in this parser I suggest that we let it parse all java github projects. Then we could group the resulting errors (if there exists any ;-)) per error type, write tests for these edge cases and then fix them. If all of the java git hub projects can per parsed without errors then we could be really sure this parser can is at least to parse the edge cases without exceptions. For sure, we don't know if the result makes sense but at least it produces a result.

Getting the download url for all java github projects is very easy:
     

Further optional parameters for this url for paging: {&page,per_page,sort,order}. Documentation for this request: https://developer.github.com/v3/search/#search-repositories

How do you think about it?

Best regards
