【问题描述】：
我有一个自定义 Gradle 插件的工作版本。我有几个单元测试，现在我正在尝试使用 nebula-test 进行集成测试。
我在集成测试中遇到了一个令人困惑的测试错误。我在使用 nebula-test 的方式上一定做错了。
我将展示完整的代码，但我将首先描述基本要素。
插件定义了一个扩展块，其中包含一些属性，其中一个是可以找到特定文件的文件路径。对于上下文，该属性名称称为“yangFilesRootDir”。
插件创建一个名为“YangGenerate”的自定义任务的实例。该任务有一个名为“yangFilesRootDir”的 File 类型的实例变量，该实例变量上有一个 @InputDirectory 注释。该任务还有其他实例变量，其中一些带有“@Input...”注释。
任务有一个“init”方法，在项目评估后从插件中调用。这会根据扩展块中的值初始化任务实例变量。在“init”方法中，如果扩展块中没有设置“yangFilesRootDir”属性，我使用默认值“src/main/yang”。
在进行此集成测试之前，我设置了一个引用该插件的独立项目。该项目的“build.gradle”指定了扩展块，并且我已经使用属性设置和不使用属性设置对其进行了测试（我将文件存储在默认位置），它工作正常。
这就是我的规范现在的样子：
class YangPluginIntegSpec extends IntegrationSpec {
def 'simple'() {
createFile("src/main/yang/dummy")
writeHelloWorld("com.example")
buildFile << applyPlugin(YangPlugin)
buildFile << '''
yang {
yangFilesRootDir 'src/main/yang'
}
'''.stripIndent()
when:
ExecutionResult result = runTasksSuccessfully('build')
then:
println result
}
}
我在有和没有“yang”块的情况下都试过了，但这个堆栈跟踪测试失败了：

我还用“-i”运行了它，以便获得更多信息，它向我显示了用于测试的临时构建目录的路径，并且在测试失败后我验证了“src/main/yang/dummy " 存在于测试项目目录中。
插件类的相关代码如下：
class YangPlugin implements Plugin<Project> {
public void apply(Project project) {
YangExtension yang = project.extensions.create(YANG_EXT, YangExtension, project)
YangGenerateTask task = project.task(YANG_GENERATE_TASK, type: YangGenerateTask)
project.afterEvaluate {
task.init(project, yang)
project.compileJava.dependsOn task
if (task.yangFilesRootDir && task.yangFilesRootDir.exists()) {
Jar jarTask = project.jar
if (task.yangFilesRootDir.getPath().startsWith(FilenameUtils.normalize(SRC_MAIN_RESOURCES))) {
jarTask.exclude(task.yangFilesRootDir.getPath() - FilenameUtils.normalize(SRC_MAIN_RESOURCES))
}
jarTask.from(task.yangFilesRootDir) { into(META_INF_YANG) }
}
}
}
}
以及YangGenerate任务的相关部分：
class YangGenerateTask extends DefaultTask {
private static final String DEFAULT_YANG_FILES_ROOT_DIR = "src/main/yang"
Project project
Collection<CodeGeneratorConfig> generators
boolean inspectDependencies
Collection<String> excludeFiles
String yangFilesConfiguration
String generatorsConfiguration
Pattern yangFilePattern = Pattern.compile("META-INF/yang/.*\\.yang\$")
@InputDirectory
File yangFilesRootDir
@Input
def getGeneratorClasses() {
...
}
@InputFiles
def getOptionalYangClasspath() {
...
}
@OutputDirectories
def getOutputDirectories() {
...
}
@TaskAction
void generate() {
...
}
public void init(Project project, YangExtension yang) {
this.yangFilesRootDir = new File(yang.yangFilesRootDir ?: DEFAULT_YANG_FILES_ROOT_DIR)
...
}
}
更新：
终于想到在调试器中运行这个测试，发现找不到路径的原因是“当前目录”不是测试项目的基目录，而是主目录的基目录插件项目，肯定没有“src/main/yang”目录。
