Still can't use google-java-format with Java 17

[christopher-cudennec]

According to the changelog we should be able to use spotless with google-java-format and Java 17 without adding extra --add-export flags to the gradle.properties.

Unfortunately it still does not work:

...
Caused by: java.lang.IllegalAccessError: class com.google.googlejavaformat.java.JavaInput (in unnamed module @0x206885a0) cannot access class com.sun.tools.javac.parser.Tokens$TokenKind (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.parser to unnamed module @0x206885a0

Using

• Gradle 7.4.2
• Spotless Gradle 6.7.0
• googleJavaFormat enabled with default version (1.15.0)
• MacOS 12.4

[georgespalding]

I got it working with gradle by specifying 1.15.0 for google-java-format; See https://github.com/diffplug/spotless/tree/main/plugin-gradle#google-java-format

Excerpt from my build.gradle

plugins {
  // ...
  id 'com.diffplug.spotless' version '6.7.0'
}

// ...

spotless {
  java {
    googleJavaFormat('1.15.0')
  }
}

Works for me after removing --add-exports and --add-opens.

As a sanity check I temporarily reverted back to 1.14.0 which breaks with Caused by: java.lang.IllegalAccessError: class com.google.googlejavaformat.java.JavaInput (in unnamed module ...) cannot access class com.sun.tools.javac.parser.Tokens$TokenKind (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.parser to unnamed module ...

EDIT: I had also updated jackson (used in my project) to 2.13.3+blackbird to make it work. Temporarily reverting to 2.13.2+afterburner made it fail. I attribute this to jackson internals, but I'm not at all sure about why.
TL;DR: To me it looks like what dependencies your code uses and how they work, affect spotless and you might still need additional --add-exports and --add-opens?

EDIT#2: I'm not so sure about my previous statement about jackson being part of the mix. I suspect the behaviour was related to what gradle daemon was used (I think I had a couple running in the background)

I also tested using googleJavaFormat('1.15.0') to double-check but I still see the same error. This is the full stacktrace:

I can't see any Jackson in the stacktrace. Why do you think it is connected to the Jackson version?
My project still uses Jackson 2.13.2.2. I will try to update it and see if it works then.

[georgespalding]

One observation (that 🤦'd me) is that spotlessApply caches the result if it completed ok previously, so after changing org.gradle.jvmargs in gradle.properties you need to ./gradlew clean spotlessApply in order to get spotless to actually execute.

[georgespalding]

Maybe #1228 has something to do with this?

[christopher-cudennec]

Hmm... Isn't it an issue for google-java-format? They are using a class from module jdk.compiler that is not exported (com.sun.tools.javac.parser.Tokens.TokenKind).
https://github.com/google/google-java-format/blob/v1.15.0/core/src/main/java/com/google/googlejavaformat/java/JavaInput.java#L37

On the other hand I can see in the diff of the 1.15.0 release that they add --add-exports=jdk.compiler/com.sun.tools.javac.parser in their pom.xml:
google/google-java-format@ee81afc

I'm not an expert in modules / exports. How is this supposed to work when spotless invokes the google-java-format main class?

[nedtwigg]

Fixed in plugin-gradle 6.7.1 and plugin-maven 2.22.7.
