plugin-under-test-metadata.properties當在IDEA中運行測試時不由Gradle TestKit創建

Question

我正在使用Gradle 3.3並嘗試使用JUnit和Gradle TestKit測試自定義插件。在插件的build.gradle我

version '0.1' 

apply plugin: 'groovy' 
apply plugin: 'java-gradle-plugin' 

sourceCompatibility = 1.8 

repositories { 
    mavenCentral() 
} 

dependencies { 
    compile project(':codegen-core') 
    compile localGroovy() 
    testCompile 'junit:junit:4.12' 
} 

測試是

package com.huawei.odmf.codegen.gradle 

import org.gradle.testkit.runner.BuildResult 
import org.gradle.testkit.runner.GradleRunner 
import org.gradle.testkit.runner.TaskOutcome 
import org.junit.Before 
import org.junit.Rule 
import org.junit.Test 
import org.junit.rules.TemporaryFolder 

import static org.junit.Assert.* 

class TestOdmfCodegenPlugin { 

    @Rule 
    public final TemporaryFolder testProjectDir = new TemporaryFolder() 

    private File buildFile 
    private File assetsDir 

    @Before 
    void setUp() { 
     buildFile = testProjectDir.newFile("build.gradle") 
     assetsDir = testProjectDir.newFolder("src", "main", "assets") 
    } 

    @Test 
    void testPlugin() { 
     buildFile << """ 
      plugins { 
      id 'com.huawei.odmf' 
     } 

     apply plugin: 'com.android.application' 

     odmf { 
      modelFile 'odmf.xml' 
     } 
     """ 

     BuildResult result = GradleRunner.create(). 
       withProjectDir(testProjectDir.root). 
       withArguments(OdmfCodegenPlugin.taskName). 
       withPluginClasspath(). 
       build() 

     // assertions 
    } 
} 

在src/main/resources/META-INF/gradle-plugins/com.huawei.odmf.properties我

implementation-class=com.huawei.odmf.codegen.gradle.OdmfCodegenPlugin 

這似乎是所有這一切根據https://docs.gradle.org/current/userguide/test_kit.html#sub:test-kit-automatic-classpath-injection和automaticClasspathInjectionQuickstart樣品所需。

然而，這個測試失敗在withPluginClasspath()（編輯：在IDEA中運行時，它的命令行工作）與以下堆棧跟蹤（我的理解，plugin-under-test-metadata.properties是應該建立由java-gradle-plugin自動）：

我錯過了什麼？

Answer 1

確定問題後在IDEA只是，我發現https://plugins.gradle.org/plugin/com.palantir.idea-test-fix並添加

plugins { 
    id "com.palantir.idea-test-fix" version "0.1.0" 
} 

到build.gradle該插件子項目開始。它解決了這個問題。

在this post (Russian)，我找到了另一種解決方案：在Settings-> Build-> Build Tools->Gradle->Runner，選擇Gradle Test Runner代替Platform Test Runner，然後再運行它之前刪除測試的運行/調試配置。
