ConfigurationLocation is modified on project open to not point to file

[proteus-russ]

This may be related to #430 although this is a relatively new change in behavior.

It is adding a "../" every time the project is opened.

I have a configuration location as follows

<ConfigurationLocation id="68dfd152-966e-457b-b366-14e5ff035aa9" type="PROJECT_RELATIVE" scope="All" description="Some Coding Conventions">
  $PROJECT_DIR$/../config/checkstyle/checkstyle.xml
  <option name="properties">
    <map>
      <entry key="basedir" value="/" />
    </map>
  </option>
</ConfigurationLocation>

Once I open a project the configuration location is changed to

<ConfigurationLocation id="68dfd152-966e-457b-b366-14e5ff035aa9" type="PROJECT_RELATIVE" scope="All" description="Some Coding Conventions">
  $PROJECT_DIR$/../../config/checkstyle/checkstyle.xml
  <option name="properties">
    <map>
      <entry key="basedir" value="/" />
    </map>
  </option>
</ConfigurationLocation>

The next time

<ConfigurationLocation id="68dfd152-966e-457b-b366-14e5ff035aa9" type="PROJECT_RELATIVE" scope="All" description="Some Coding Conventions">
  $PROJECT_DIR$/../../../config/checkstyle/checkstyle.xml
  <option name="properties">
    <map>
      <entry key="basedir" value="/" />
    </map>
  </option>
</ConfigurationLocation>

and so on

<ConfigurationLocation id="68dfd152-966e-457b-b366-14e5ff035aa9" type="PROJECT_RELATIVE" scope="All" description="Some Coding Conventions">
  $PROJECT_DIR$/../../../../../../config/checkstyle/checkstyle.xml
  <option name="properties">
    <map>
      <entry key="basedir" value="/" />
    </map>
  </option>
</ConfigurationLocation>

The only way to run checkstyle is to rollback the changes made to the configuration on startup and then reload the config file.

Those whom the Gods wish to destroy, they first send file handling in IDEA. I've failed to reproduce this, but given the continual problems with anything that relies on IDEA's magic PROJECT_DIR, I've no doubt at all that there's something awry. The logic around what the project directory is gets messier and messier with every IDEA release.

Could you please give me any information on your environment that might be relevant? e.g. OS, project layout (are you using an ipr file or .idea, is it a simple <project>/.idea or something multi-module/more complicated, ...?), ...?

For reference, I'm working on Mac OS 12.6, IDEA 2022.2.2, with a simple structure:

project/.idea/checkstyle-idea.xml
config/relative-test.xml

I think I'm seeing this issue on our project.

Where we have a shared .idea folder committed to version control, we use a fairly standard multi-module maven setup.
The checkstle config file is stored in ${PROJECT_ROOT_DIR}/etc/checkstyle-custom_checks.xml However we are seeing

diff --git a/.idea/checkstyle-idea.xml b/.idea/checkstyle-idea.xml

(looking at the diff we have already committed once with an extraneous .. in it.

Not entirely sure when the change is happening (I think it's on commit rather than project open)
