用IntelliJ调试Gradle插件

Question

我想使用IntelliJ的交互式调试器。 <罢工> 不幸的是，我无法说服IntelliJ加载和编译插件。然而, 我可以执行gradle clean build并且插件按照预期构建并运行其测试。

具体地说，我正在尝试调试对gradle-js-plugin的本地更改 <罢工> IntelliJ说它找不到 com.google.javascript.jscomp.CompilerOptions以及 spock.lang.specification。（我在想也许是因为它们的装填方式，但那只是猜测。）

import org.gradle.GradleLauncher

class GradleScriptRunner {
    public static void main(String[] args) {
        GradleLauncher.newInstance(
            "-p", 
            "/path/to/gradle-js-plugin/src/test/resources/build.gradle", 
            "clean assemble"
        )
    }
}

1. ~#cd/path/to/gradle-js-plugin&&gradle cleanIdea idea
2. 打开了新创建的项目，并尝试使用步骤0中的ScriptRunner进行调试。

结果：项目编译（耶！），但我只能在gradlescriptrunner.groovy中找到断点。

1和2。为清晰起见合并：

~# export GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"
~# gradle clean assemble
Listening for transport dt_socket at address: 5005

对于这一步，我尝试了以下.gradle文件配置：

1.仅使用Build.Gradle

--Build.Gradle--

apply plugin: 'groovy'
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'maven'
apply plugin: 'js'

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        compile findProject "/path/to/gradle-js-plugin"
    }
}

repositories {
    mavenLocal()
    mavenCentral()
}

FAILURE: Build failed with an exception.

* Where:
Build file '/path/to/gradle-js-plugin/src/test/resources/build.gradle' line: 13

* What went wrong:
A problem occurred evaluating root project 'resources'.
> No such property: findProject for class: org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler

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

}

    mavenCentral()
}

IntelliJ IDEA Ultimate 117.499 w/ Bundled Gradle plugin

任何可以让我进入插件调试模式的提示。

Answer 1

首先，听起来你的IDEA Gradle项目有问题。如果您运行gradlew cleanIdea IDEA，然后从IDEA打开生成的项目（而不是使用JetGradle插件），那么一切都应该很好。

其次，如果您仍然无法使GradleMain/GradleLauncher（前一个类确实存在）方法工作，另一种方法是将Gradle构建作为外部应用程序进行调试。为此，您需要将-xdebug-xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005添加到gradle_opts环境变量中，从命令行运行构建，等待它挂起，然后从idea启动“远程”运行配置（具有相应的设置）。此时，调试器应该连接到Gradle进程，并且您应该启动并运行。
