Hi,

I created test cases out of the ArgoUML and Guava systems.

There is still a problem with spring-core, but I did not figure it out yet.

Nevertheless, it would be great if you could try again and perhaps extend the analysis to other systems.

@Meinert: one thing that would be cool even if we do not have the all github would be to prepare a set of scripts like you offered for the Guava case. The thing is that for Guava, I tried to get the Maven dependencies and it did not work (at least not on the head of development). This means that I could not see what happens in the best case scenario when we have all libraries and we can resolve the dependencies.

What do you think?

Cheers,

Doru

Wie analysing guava I had similar problems:

cd guava

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

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

Exception in thread "main" java.lang.ClassCastException: org.eclipse.jdt.core.dom.EnumConstantDeclaration cannot be cast to org.eclipse.jdt.core.dom.ClassInstanceCreation

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:

  https://api.github.com/search/repositories?q=language:Java

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

Meinert
