When opening the preferences, I get an error saying Unable to create the selected preference page.

My PMD Plug-in Version is 4.11.0.v20200312-1712. It was freshly installed into eclipse 2019-06 (4.12.0) this morning.

That's about the log settings. Can you share the following file from your workspace? .metadata/.plugins/org.eclipse.core.runtime/.settings/net.sourceforge.pmd.eclipse.plugin.prefs

You should be able to get back to a working state with the following steps:

  1. exit eclipse
  2. modify .metadata/.plugins/org.eclipse.core.runtime/.settings/net.sourceforge.pmd.eclipse.plugin.prefs in your workspace: remove the property "net.sourceforge.pmd.eclipse.plugin.log_filename"
  3. start eclipse
  4. configure the filename to log to again via the preferences
andipabst commented

There is no such file in my workspace. This error occurred when I first tried to open the settings, so I could never change them in any way.

adangel commented

Did you create a new workspace or reused an existing one? Do you use oomph? Do you have a file "C:/Users/andipabst/.eclipse/org.eclipse.oomph.setup/setups/user.setup"?

andipabst commented

I tried it with an existing and a new workspace, the problem occurs both times. I did not (knowingly) use oomph. Yes, such a file is present, it contains a couple of <acceptedLicense> fields. I attached the file (renamed to .txt, since GitHub would not allow me to upload .setup files).

user.setup.txt

adangel commented

Here's the default value for the preference:

pmd-eclipse-plugin/net.sourceforge.pmd.eclipse.plugin/src/main/java/net/sourceforge/pmd/eclipse/runtime/preferences/IPreferences.java

Line 36 in ff53cf9

String LOG_FILENAME_DEFAULT = System.getProperty("user.home") + "/pmd-eclipse.log";

I found where the ".%i" comes from:

pmd-eclipse-plugin/net.sourceforge.pmd.eclipse.plugin/src/main/java/net/sourceforge/pmd/eclipse/logging/internal/LogbackConfiguration.java

Line 90 in ff53cf9

rollingPolicy.setFileNamePattern(logFileName + ".%i");

That would mean, there are some incompatible logback version in your eclipse installation. I'm using eclipse 2019-12 (4.14.0) and have no problems...

andipabst commented

I upgraded eclipse to 2019-12 (4.14.0) as well, now the error is gone. So apparently it seems to have been the logback version. Thanks for your quick help.
