Warnings during analysis

SonarQube

Hi,

I am currently running SQ 7.6 with Findbugs plugin version 3.11.1 and seeing the below warnings in our sonar analysis runs.
The job goes through fine but there are a lot of similar warnings we see in the logs.

[WARNING] Failed to load the class file metadata

Can you please have a look and let us know how to resolve this issue.

[WARNING] The class ‘com.Test’ could not be matched to its original source file. It might be a dynamically generated class.

This is seen at the top of the trace pasted above

Hi,

This is coming from the FindBugs plugin, so you need to raise the question in a GH issue on the plugin.

Hi Ann,

Our code structure is like below
src/main/java which contains all the source code and
src/test/java which contains the corresponding test code for the above files.

When we make the changes as shown in the below picture(under Administration -> General Settings -> Analysis Scope), all the warnings as mentioned in the question(related to java files under src/test/java) all go away.
