使用 gradle 项目时出现 Eclipse 错误

Question

我尝试在 Eclipse 中使用我的 gradle 项目，但出现以下错误

 Synchronize Gradle projects with workspace failed due to an unexpected error.
Cannot nest 'iC/src/java' inside 'iC'. To enable the nesting exclude 'src/' from 'iC'
Java Model Exception: Java Model Status [Cannot nest 'iC/src/java' inside 'iC'. To enable the nesting exclude 'src/' from 'iC']

我已将错误范围缩小到这段黑色代码

sourceSets{
    test {
        resources {
            srcDirs = [projectDir]
                ['.gradle','build.gradle','gradle','gradlew','gradlew.bat','bin','branding','compsciBuild','db','html','images','jsp','logs','META-INF','scripts','src','styles','theme','web','WEB-INF','build','.svn','reports'].each{excludes->
                exclude excludes
            }
        }
    }
}

我不知道必须重写该块才能让我的 junit 测试正常运行。如果我只包含

sourceSets.test.resources.srcDirs = ["${projectDir}/data"]

在我的 junit 日志中是以下内容

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'autopilot' defined in URL [file:etc/applicationContext-parsing.xml]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.compsci.ic.parser.rr.Autopilot]: Constructor threw exception; nested exception is java.io.FileNotFoundException: class path resource [data/autopilotCorpus] cannot be resolved to absolute file path because it does not exist

我知道我可以重写 junit 测试以更明确地说明他们在哪里寻找数据文件夹，但目前这不是一个选项，因为在我们做出切换之前，一些开发人员仍在使用 ant。

提前致谢。

文件夹结构如下

projectDir/src/java
projectDir/test/src/java
projectDir/data

* **更新 ***

我最终按照@M.Ricciuti 的建议解决了这个问题。我的最终工作代码如下所示

sourceSets{
    test {
        resources {
            srcDirs = [projectDir]
            ['.gradle/','build.gradle','gradle/','gradlew','gradlew.bat','bin/','branding/','compsciBuild/','db/','html/','images/','jsp/','logs/','META-INF/','scripts/','src/','styles/','theme/','web/','WEB-INF/','build/','.svn/','reports/', 'test/', '*.*', 'etc/', 'lib/', '.settings/'].each{excludes->
                exclude excludes
            }
        }
    }
}

通过配置测试SourceSets“资源”目录，您使用了正确的方法使测试资源可用。

但是你的排除规则有两个小错误：

• 您需要在排除目录列表中添加test目录
• 您忘记了结尾的 '/' 字符（写 'src/' 而不是 'src'）
