I've added the following to my eclipse.ini to no avail:

--illegal-access=deny
--add-opens java.base/java.lang=ALL-UNNAMED
--add-opens java.base/java.util=ALL-UNNAMED
--add-exports jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED

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

I have the same Problem...

commented

It should not be --add-exports EXPORT, but instead --add-exports=EXPORT.
When I correctly use the = sign there does not seem to be an error anymore:

--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.util=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED

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

It looks like the root of this issue is:

google-java-format/core/src/main/java/com/google/googlejavaformat/java/JavaInput.java

Line 37 in 27670be

import com.sun.tools.javac.parser.Tokens.TokenKind;
not being exported by java17.

I have the same problem with:
v1.15.0 (but the Eclipse plugin's jar is called google-java-format-eclipse-plugin-1.13.0.jar)
Version: 2022-06 (4.24.0)
Build id: 20220609-1112

To be able to use the plugin in Eclipse I downgraded to tag v1.11.0 [https://github.com/google/google-java-format/releases/tag/v1.11.0], and make sure in eclipse.ini you are pointing to java 11.

commented

Same here, with v1.15.0. Any updates?

Workaround.
v1.13.0 seems to load fine.

Environment (default eclipse install; using the new installer)

eclipse.buildId=4.26.0.20221201-1200
java.version=17.0.5
java.vendor=Eclipse Adoptium
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US
Framework arguments: -product org.eclipse.epp.package.jee.product
Command-line arguments: -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.jee.product

commented

For me as well, version 1.13.0 works but 1.15.0 does not on Eclipse with Java 17 even though I have the flags in eclipse.ini. I even have more flags than what should be necessary:

--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.util=ALL-UNNAMED
--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED
--add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED
--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.main=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED
--add-exports=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED

Note that testing this is a little bit tricky due to #744 (comment).

Same Issue with IntelliJ

I only have the following VM options:

--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.util=ALL-UNNAMED
--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.parser=ALL-UNNAMED
--add-exports jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED
--add-exports jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED

Clearly the above does not prevent the issue. I will now try the list as from @PhillippWendler to see if that improves things...

Current versions of the plugin (e.g., 1.18.1) work fine for me in Eclipse with Java 17.

Which version of Eclipse are you running? I am still facing the error with the latest version (1.18.1) of the plugin (stack trace copied below).

Do you have the additional options in eclipse.ini that are discussed above?

commented

I tried with and without the additional eclipse.ini configured and it still doesn't work. I have a fairly standard Eclipse installation (I have lombok installed, but that's about it).

As a temporary measure, I imported the configuration provided here.

Following patch worked for me in Eclipse 2023-09 and Google Code Formatter plugin version 1.18.1:

I wonder why this wasn't added to the installation instruction already a long time ago? Similar information is contained in the IntelliJ setup instructions (even though there less whitelisting seems to suffice...)
