   @git-code-for-me I had the exact same problem today. Apparently it's very important that you put a newline at the end of you .vmoptions file otherwise the last option gets concatenated with some other options that idea is adding.

   fix google#940 Update README.md - new line is important for .vmoptions

   This issue will close once commit c2e19cb is merged into the 'master' branch.

   I've having same issue, idea 2023.2.4
   Running on intel mac.
   openjdk version "17.0.9" 2023-10-17

   Keep getting the popup every time start IDE saying to configure the jre for google-java-format

   Formatting doesn't work at all. The preview window in Code Style doesn't update with config changes.

   Checked idea.log , and can't see anything to explain why this isn't loading, not errors or warning, just single line saying loaded plugin:

   2023-11-02 08:56:58,416 [ 241] INFO - #c.i.i.p.PluginManager - Loaded custom plugins: google-java-format (1.17.0.0), Save Actions - XDEV Edition (1.0.4)

   idea.vmoptions

   -Xmx2048m
   --add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED
   --add-exports=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED
   --add-exports=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED

   --add-exports=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED
   --add-exports=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED
   

   Is there anywhere else to get logs or diagnostics on why this plugin isn't loading properly?

   Can you see if those options are actually being applied to the JVM? For example, if you do a ps auxw | grep idea.Main, do you see those options (all six of them) being passed to the JVM?

   (Sorry, I don't have a Mac, so I don't know if ps auxw actually works there, but I think it should...)

   So looks like issue with intellij on mac, not the plugin (not picking up vm options).

   Instead, I editted:
   /Applications/IntelliJ\ IDEA\ CE.app/Contents/Info.plist

   Found this section:

   <key>JVMVersion</key>
         <string>1.8*,1.8+</string>
         <key>MainClass</key>
         <string>com/intellij/idea/Main</string>
         <key>ErrorFile</key>
         <string>-XX:ErrorFile=$USER_HOME/java_error_in_idea_%p.log</string>
         <key>HeapDump</key>
         <string>-XX:HeapDumpPath=$USER_HOME/java_error_in_idea.hprof</string>
         <key>Options</key>
         <array>
           <string>--add-opens=java.base/java.io=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.lang=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.lang.ref=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.lang.reflect=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.net=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.nio=ALL-UNNAMED</string>
           <string>--add-opens=java.base/java.nio.charset=ALL-UNNAMED</string>
          ....
   

   and at the end of that array, added the other strings

           <string>--add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED</string>
           <string>--add-exports=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED</string>
           <string>--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED</string>
           <string>--add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED</string>
   

   Restarted, and now works as expected!

   Hmm... so raised with Intellij, but they said vm options are loading correctly, so maybe issue with plugin not picking up options correctly?

    Current releases of the IntelliJ plugin target IntelliJ 2025.1+ (which bundles JBR 21) and configure the required JVM exports automatically when installed from the JetBrains Marketplace: https://github.com/google/google-java-format#intellij-android-studio-and-other-jetbrains-ides.
