Error Running MUnit Tests in Mulesoft: NoSuchFieldError: JAVA_21

I'm having a problem.

I'm new to the MuleSoft world and I'm creating a Mule Connector for my company. I downloaded Anypoint Studio 7.21 and created a new project with my connector code.

My project runs fine; I can create a new project, use my connector in the flow, and it works well. However, when I right-click on my project and go to MUnit -> Configure MUnit Maven Support, the IDE adds the following lines to my pom.xml:

<properties>
    // other properties
    <munit.version>3.4.0</munit.version>
</properties>

<build>
    <plugins>
        // other plugins
        <plugin>
                <groupId>com.mulesoft.munit.tools</groupId>
                <artifactId>munit-maven-plugin</artifactId>
                <version>${munit.version}</version>
                <executions>
                    <execution>

                            <goal>coverage-report</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <coverage>
                        <runCoverage>true</runCoverage>
                        <formats>
                            <format>html</format>
                        </formats>
                    </coverage>
                </configuration>
            </plugin>
    </plugins>
</build>

<dependencies>
    // other dependencies
    <dependency>
        <groupId>com.mulesoft.munit</groupId>
        <artifactId>munit-runner</artifactId>
        <version>3.4.0</version>
        <classifier>mule-plugin</classifier>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>com.mulesoft.munit</groupId>
        <artifactId>munit-tools</artifactId>

        <artifactId>assertions</artifactId>
        <version>1.2.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

I then created an empty test case for my connector, but when I run the test, the IDE shows me this error:

package org.mule.extensions.oldcoats;

import org.mule.functional.junit4.MuleArtifactFunctionalTestCase;

public class OldCoatsTestCase extends MuleArtifactFunctionalTestCase {

}

When I execute the test, the IDE shows me this error:

The problem is, I'm not using JAVA_21 in my code, and I don't know what this JAVA_21 is. My project is using Java 17, and I'm using Anypoint Studio 7.21.

This is my JAVA_HOME:

openjdk version "17.0.13" 2024-10-15
OpenJDK Runtime Environment Temurin-17.0.13+11 (build 17.0.13+11)
OpenJDK 64-Bit Server VM Temurin-17.0.13+11 (build 17.0.13+11, mixed mode, sharing)

And this is my maven version:

Apache Maven 3.9.9 (8e8579a9e76f7d015ee5ec7bfcdc97d260186937)
Maven home: C:\ProgramData\chocolatey\lib\maven\apache-maven-3.9.9
Java version: 17.0.13, vendor: Eclipse Adoptium, runtime: C:\Program Files\Eclipse Adoptium\jdk-17.0.13.11-hotspot

I don't know what is happening, and I don't know how to fix this error. I tried to downgrade the MUnit version to 3.3.0, but the error persists.

This is my pom.xml:

This is my mule-artifact.json file:

{
  "minMuleVersion": "4.9.0",
  "javaSpecificationVersions": [
    "17"
  ]
}

And this is my Module class:

package com.oldcoats.mule.internal.modules;

import com.oldcoats.mule.configurations.OldCoatsConfigurationBase;
import com.oldcoats.mule.errors.OldCoatsErrorBase;

import org.mule.runtime.api.meta.Category;
import org.mule.runtime.extension.api.annotation.Configurations;
import org.mule.runtime.extension.api.annotation.Extension;
import org.mule.runtime.extension.api.annotation.dsl.xml.Xml;
import org.mule.runtime.extension.api.annotation.error.ErrorTypes;

import org.mule.sdk.api.annotation.JavaVersionSupport;
import org.mule.sdk.api.meta.JavaVersion;

@Xml(prefix = "oldcoats")
@Extension(name = "OldCoatsConnector", vendor = "OldCoats", category = Category.COMMUNITY)
@JavaVersionSupport({JavaVersion.JAVA_8, JavaVersion.JAVA_11, JavaVersion.JAVA_17})
@Configurations({OldCoatsConfigurationBase.class})
@ErrorTypes(OldCoatsErrorBase.class)
public class OldCoatsModule {

}

All the versions in the pom.xml are added automatically by the IDE when I click on MUnit -> Configure MUnit Maven Support or when I create the project.

I don't know what is happening, and I don't know how to fix this error.

Also, I'm not sure if is a problem in my machine, because the pipeline also fails with the same error. This is the code to run the pipeline:

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:
- task: Maven@4
  inputs:
    mavenPomFile: 'pom.xml'
    mavenOptions: '-Xmx3072m'
    javaHomeOption: 'JDKVersion'
    jdkVersionOption: '1.17'
    jdkArchitectureOption: 'x64'
    publishJUnitResults: true
    testResultsFiles: '**/surefire-reports/TEST-*.xml'
    goals: 'package'

Can someone help me, please?

The error happens because you are using dependencies for Mule applications in a Mule connector project.

MUnit is not designed to be used to test connectors projects. It is a testing framework for applications. For unit testing a connector you use MuleArtifactFunctionalTestCase and JUnit, as the test class in the question.

Also other connectors should not be used as dependencies in a Mule Java connector project. Those are also meant to be dependencies for Mule applications, like your own custom connector.
