Copy libraries from project directory functionality seems not working

[remal]

We have a custom checkstyle-extensions.jar at the root of our project.

Our .idea/checkstyle-idea.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="CheckStyle-IDEA">
    <option name="configuration">
      <map>
        <entry key="active-configuration" value="PROJECT_RELATIVE:C:/Users/remal/project/checkstyle.xml:Project checkstyle" />
        <entry key="checkstyle-version" value="9.3" />
        <entry key="copy-libs" value="true" />
        <entry key="location-0" value="BUNDLED:(bundled):Sun Checks" />
        <entry key="location-1" value="BUNDLED:(bundled):Google Checks" />
        <entry key="location-2" value="PROJECT_RELATIVE:C:/Users/remal/project/checkstyle.xml:Project checkstyle" />
        <entry key="scan-before-checkin" value="false" />
        <entry key="scanscope" value="JavaOnlyWithTests" />
        <entry key="suppress-errors" value="true" />
        <entry key="thirdparty-classpath" value="$PROJECT_DIR$/checkstyle-extensions.jar" />
      </map>
    </option>
  </component>
</project>

When we change checkstyle-extensions.jar we see that this file is locked by a Java process, that's why I think "Copy libraries from project directory" functionality isn't working.

Are there any ideas? How can I debug this functionality myself?

Operation system: Windows Project path: C:\Users\remal\project

The copy libraries feature only deals with the module classpath, which is basically the libraries your application uses.
If you also want your third-party Checkstyle addons outside the project, you must simply place them outside the project. 😄

We commit third-party checks in our Git repository. Is it possible to copy them too?

It's not at present, support would need to be added. We know the paths, so it shouldn't be too hard in principle.

[remal]

Sorry if I didn't understand you correctly. If it's not so hard, are you going to implement it?

[jshiell]

No current plans myself, given I don't have a Windows machine to test on, nor much inclination to work on this. But it should be easy enough in principle if someone wants to submit a PR.
