ktlint: java.lang.reflect.InaccessibleObjectException: Unable to make field private transient java.lang.Object java.lang.Throwable.backtrace accessible: module java.base does not "opens java.lang" to unnamed module @76628072

Expected Behavior

The task should tell me if there is a problem with the code style or not.

Observed Behavior

        }
    }
    // additional 3rd party ruleset(s) can be specified here
    // just add them to the classpath (e.g. ktlint 'groupId:artifactId:version') and
    // ktlint will pick them up
}

    description = "Check Kotlin code style."
    classpath = configurations.ktlint
    mainClass.set("com.pinterest.ktlint.Main")

    // to add a baseline to check against prepend following args:

    // see https://github.com/pinterest/ktlint#usage for more

Thanks @paul-dingemans, @cwilper Temporarily fixed by adding the following line to my ktlinFormat definition

task ktlintFormat(type: JavaExec, group: "formatting") {
    ...
    jvmArgs "--add-opens=java.base/java.lang=ALL-UNNAMED"
}

ch4rl3x on Nov 30, 2022

Sorry, I was just running the ktlint CLI version which worked fine. Tnx for pointing once more to ./gradlew ktlintFormat which does reproduce the problem. Based on @cwilper’s comment, I got it working by changing the definition of the ktlintFormat task as follows:

val ktlintFormat by tasks.creating(JavaExec::class) {
    inputs.files(inputFiles)
    outputs.dir(outputDir)

    description = "Fix Kotlin code style deviations."
    classpath = ktlint
    jvmArgs = listOf("--add-opens=java.base/java.lang=ALL-UNNAMED")
    setProperty("mainClass", "com.pinterest.ktlint.Main")
    args = listOf("-F", "src/**/*.kt")
}

paul-dingemans on Sep 19, 2022

For maven users it is possible to get around this by adding a file .mvn/jvm.config with content --add-opens java.base/java.lang=ALL-UNNAMED, e.g.:

$ mkdir -p .mvn
$ echo "--add-opens java.base/java.lang=ALL-UNNAMED" > .mvn/jvm.config

I am not sure whether OP’s original problem is solved, but I am loosing track on the status of this issue.

The problem is caused by newer Java version restricting access to certain libraries. We have to wait until libraries we use, do solve this problem so that it does not propagate via KtLint. Providing the --add-opens=java.base/java.lang=ALL-UNNAMED in one of ways suggested before is the way to go for now.

paul-dingemans on Dec 3, 2022

@paul-dingemans I have created a sample repository with the same issue here.

I am facing this issue with

java --version openjdk 17.0.4 2022-07-19 LTS OpenJDK Runtime Environment Corretto-17.0.4.8.1 (build 17.0.4+8-LTS) OpenJDK 64-Bit Server VM Corretto-17.0.4.8.1 (build 17.0.4+8-LTS, mixed mode, sharing)

ktlintFormat works when using with java 11 (though gives a warning as mentioned here: https://github.com/pinterest/ktlint/issues/1618), but if there is some code formatting issue, then ktlintFormat fails with the above version, and may be other java versions as well.

try this, this work well for me. I alse encounter this problem in jdk 17.

- JVM_OPTS= --add-exports=java.naming/com.sun.jndi.ldap=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.security=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.management/javax.management=ALL-UNNAMED --add-opens=java.naming/javax.naming=ALL-UNNAMED

buttercannfly on Jul 12, 2022

Hello, here’s another data point on this: I got the same error when trying to run ktlint 0.45.2 from Java 17 in gradle. I eventually got around it by setting these jvmArgs in my JavaExec task.

  jvmArgs '--add-opens' 'java.base/java.lang=ALL-UNNAMED'

Fwiw, I also did not run into the issue originally unless I passed the -F argument.

cwilper on Apr 7, 2022

@ScottPierce Tnx for detailed description. I will have a look at it again.
