无法使用NetBeans 8.1的Gradle支持插件构建Gradle项目

Question

我开始了一个学习项目,熟悉Gradle,Spring和Vaadin.到目前为止,我已经在一些Spring指南的帮助下成功创建了基本的CRUD功能.

现在我想将项目导入NetBeans.我为NetBeans 安装了Gradle Support插件,并将我的存储库克隆到一个新的NetBeans项目中.

当我在NetBeans中尝试build或bootRun项目时,它失败了,告诉我无法找到主类.但是当我build或者bootRun直接从命令行使用我加载到存储库的gradle包装器时,它工作正常.

我在GitHub上研究了Gradle Support插件的wiki的每一页,但找不到与我的问题相关的任何信息.

这是我尝试通过项目的上下文菜单操作Tasks/build/build在NetBeans中运行项目时得到的输出:

Executing: gradle :build

:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':findMainClass'.
> Could not find property 'main' on task ':run'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 1.957 secs



Build failure (see the Notifications window for stacktrace): gradle :build

我将提到的堆栈跟踪粘贴到Gist.

这是我在同一个项目中从命令行执行的成功构建的输出:

$ ./gradlew build
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass
:jar
:bootRepackage
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build

BUILD SUCCESSFUL

Total time: 11.673 secs

我真的不知道如何继续这个并且非常感谢任何提示,我发现从命令行运行和从NetBeans运行时得到不同的结果非常奇怪.不应该NetBeans插件只是调用我在命令行上直接使用的相同命令,并且工作正常吗？

Answer 1

我找到了两种方法来解决这个问题.

a)添加

if (!hasProperty('mainClass')) {
    ext.mainClass = 'org.foo.Bar'
}

到build.gradle.

b)将选项/其他/ Gradle /任务执行/自动任务设置为"NetBeans不应自动添加任务".

我在build.gradleNetBeans生成的文件中找到的这条评论给了我关键的提示:

// NetBeans will automatically add "run" and "debug" tasks relying on the
// "mainClass" property. You may however define the property prior executing
// tasks by passing a "-PmainClass=<QUALIFIED_CLASS_NAME>" argument.
//
// Note however, that you may define your own "run" and "debug" task if you
// prefer. In this case NetBeans will not add these tasks but you may rely on
// your own implementation.
