Gradle 7 & Java 11: No compatible toolchains found for request filter

Question

After upgrading to from Gradle 6.7.1 to Gradle 7.4, the following error occurs:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':example-project:compileJava'.
> Failed to query the value of extension 'example-extension' property 'enabled'.
   > Failed to calculate the value of task ':example-project:compileJava' property 'javaCompiler'.
      > No compatible toolchains found for request filter: {languageVersion=11, vendor=any, implementation=vendor-specific} (auto-detect true, auto-download false)

Answer 1

Solution:

Add this to build.gradle:

java {
    toolchain {
        implementation = JvmImplementation.J9
    }
}

Explanation

It turned out that the JDK I used was implemented with J9.

At the time of writing, Gradle ignores JDK implemented with J9 unless explicitly set to use it.

This appears to be a bug:

https://github.com/gradle/gradle/issues/16897#issuecomment-823272229

To check whether your JDK is implemented in J9 or not, run

path/to/your/jdk/bin/java -version

The output will look something like this:

openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.10+9)
Eclipse OpenJ9 VM AdoptOpenJDK (build openj9-0.24.0, JRE 11 Linux amd64-64-Bit 20210120_821 (JIT enabled, AOT enabled)
OpenJ9   - 345e1b09e
OMR      - 741e94ea8
JCL      - 0a86953833 based on jdk-11.0.10+9)

This doesn't solve the error: Caused by: org.gradle.api.internal.provider.AbstractProperty$PropertyQueryException: Failed to calculate the value of task ':compileJava' property 'javaCompiler'. – Sherellsherer

Answer 2

In my case, java 21 made the same problem. I installed java 17 and explicitly declared it in JAVA_HOME

If you are trying out Kotlin Multiplatform, specifically for JVM and web development, replacing this:

jvm {
        jvmToolchain(8)
        withJava()
        testRuns["test"].executionTask.configure {
            useJUnitPlatform()
        }
    }

with this:

jvm()

helped me fix the issue.

This doesn't fix the error. – Sherellsherer

In general, if you are using Kotlin look out in your gradle build files for the kotlin option that configure jvmToolchain (or toolchain if it is in java compiler options). The code author not necessarily has the same tool chain installed as you. This caused an error for me when trying to build some open source library in Android Studio – Stoned

Also make sure you don't have mismatching definitions for toolchain version – Stoned

Answer 4

In my case was a missing Java version in the IDE, just setup the correct java version (As shown in the build.gradle file) in your IDE and configure it correctly for your project
