Getting Started about gumtree

[Symbolk]

@leusonmario One solution is provided in #88, it seems the problem with ClassIndex, which replaces Reflections to scan all the generators.

Hi and thanks for your feedback.

Could you be more precise about the issues you ran over with?

Cheers.

Thanks for your reply.

So... When I run the project with or without the required dependencies, I always have the same message:

** No command given.
Available Options:
-c <2> Set global property (-c property value). Properties do not need to be prefixed by gumtree.
-v Verbose mode
--help Display help (this screen)

Available Commands:

• list: List things (matchers, generators, properties, ...)
• parse: Parse file and dump result

According to Getting Started page after adding the dependencies, all commands and parsers should be available.

Adding the dependencies and running the Run class with the command webdiff f<fileNameOne>.java <fileNameTwo>.java, I got:

** Unknown sub-command 'webdiff'.

Can you tell me how you installed GumTree?

[leusonmario]

I basically used Eclipse for configuring the project.
The project was imported as Github Repository. All projects worked well except 'benchmark'. Thus, I added a new dependency on its gradle file compile group: 'org.openjdk.jmh', name: 'jmh-core', version: '1.19'

Since all projects were configured and built correctly, I run the Run class with and without the dependencies introduced on the project classpath.

Adding all projects to the classpath, I got the following message.
I think it happens due to cycles on the build path

It was an issue with eclipse version.
I'll close this issue.

Have you tried IDEA? The same problem comes to me in IDEA so I wonder what you did to resolve it.
Thanks! @leusonmario

@Symbolk I didn't use IDEA, but eclipse IDE. I solved my issue using a new version of eclipse. You may possibly try it also.
