我在 Eclipse 中有一个简单的 Java 11 项目，具有以下依赖项：

dependencies {   
    testImplementation("org.junit.jupiter:junit-jupiter-api:${junit}")  
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:${junit}")
}

项目结构如下：

项目结构

module-info.java仅导出模块 simple.tests 中的包simple.tests。

我已经定义了以下 Gradle 任务来正确设置 Eclipse 项目及其依赖项。测试依赖项位于类路径上，这些仅对测试源可见。

eclipse {
    classpath {
        file {
            whenMerged {
                entries.findAll { 
                    it.kind == 'src' || it.kind == 'lib' 
                }.each { it.entryAttributes['module'] = 'true' }
            }
        }
    }
}

eclipse.classpath.file.whenMerged {

    // Setting output folder for main files
    def mainSrc = entries.find { it.path == 'src/main/java' }
    if(mainSrc != null) {
        mainSrc.output = 'bin/main'
    }

    def mainResources = entries.find { it.path == 'src/main/resources' }
    if(mainResources != null) {
        mainResources.output = 'bin/main'
    }

    // Setting output folder for test files
    def testSrc = entries.find { it.path == 'src/test/java' }
    if(testSrc != null) {
        testSrc.output = 'bin/test'
        testSrc.entryAttributes['test'] = 'true'
        testSrc.entryAttributes['module'] = 'false'
    }

    def testResources = entries.find { it.path == 'src/test/resources' }
    if (testResources != null) {   
        testResources.output = 'bin/test'
        testResources.entryAttributes['test'] = 'true'
        testResources.entryAttributes['module'] = 'false'
    }

    // Updating test dependencies' visibility and adding them to module path
    // instead of the classpath
    entries.forEach { entry ->
        def entryIn = { it.find { file(entry.path).equals(it) } }
        if (entry.kind == 'lib') {
            entry.entryAttributes['test'] =
               entryIn(configurations.testRuntimeClasspath) &&
                !entryIn(configurations.runtimeClasspath)
            if(entry.entryAttributes['test']) {
                entry.entryAttributes['module'] = 'false'
           }
        }
    }
}

我可以使用以下设置在 Gradle (5.0) 中编译和运行测试用例：

test {
     useJUnitPlatform()
}

ext.moduleName = 'simple.tests' 

compileJava {
    inputs.property("moduleName", moduleName)
    doFirst {
        options.compilerArgs = [
            '--module-path', classpath.asPath,
        ]
        classpath = files()  
    }
}

但是，我无法在 Eclipse 中执行 JUnit 测试，因为我收到一条错误消息（没有使用测试运行器“Junit 5”找到测试）和以下堆栈跟踪：

Class not found simple.tests.DummyTest
java.lang.ClassNotFoundException: simple.tests.DummyTest
    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583)

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:209)

将测试依赖项移动到模块路径并不能解决问题。在这种情况下，即使在将 Junit Launcher 添加到模块路径之后，我也会得到以下堆栈跟踪：

我找到的唯一解决方案是删除 module-info.java 文件。删除模块描述符后，测试用例可以在 Eclipse 和 Gradle 中执行。

我的配置中有错误的设置吗？还是我做错了什么？

先感谢您！
