Grails - 任务 bootRun 执行失败。启动进程命令 java.exe 时出现问题

Question

有一个现有的 Grails 项目，不幸的是所有参与该项目的人都离开了公司。

当我在 Windows 10 命令提示符下（不以管理员身份运行）时

gradlew bootRun --debug

我明白了

我试过了

gradlew clean build 

就像我在某处看到的推荐一样，但没有帮助。

我看过

java -version

java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) Client VM (build 25.281-b09, mixed mode, sharing)

和

grails -version
| Grails Version: 4.0.0
| JVM Version: 1.8.0_291

This article 似乎认为我的项目中应该有一个 src/main/java ，但我没有那个目录。我如何创建/获取它？我无法重建该项目，因为它很大。那篇文章提到在某处添加 sourceSets，但没有说明在哪里添加。

知道为什么它不会构建并且找不到 java，以及如何修复它？

在我的 Windows 10 环境设置中，我看到 java_home 和 java_jdk 的两个系统变量都设置为：

c:\Program Files\Java\jdk1.8.0_291

更新：也许这就是问题所在。 java -version 显示 1.8.0_281。 Java 主页是 1.8.0_291。如何让 java -version 显示正确/安装的版本？我的程序文件/Java 目录中有 1.8.0_291。

更新2： 我尝试使用双斜杠在 home/me/.gradle 目录中创建 gradle.properties 文件，因为我有错误并在link 中看到了修复：

org.gradle.java.home=C:\\Program Files\\Java\\jdk1.8.0_291

在我的 Windows 10 命令提示符窗口中，我运行并看到了这个错误：

gradlew bootRun --debug

仍然不确定是什么导致了错误。我尝试以管理员身份运行命令提示符，并看到相同的错误。

更新3：

试试这个...我在 grailsapp 文件夹中找到了 build.gradle。出于某种原因，Intellij Idea 没有显示它。我添加了这个

compileJava {
        options.fork = true 
        options.forkOptions.executable = '${JAVA_HOME}/bin/javac.exe'
}

我仍然遇到构建失败

Total time: 3.197 secs

更新5： 我的路径环境变量中有 %JAVA_HOME%\bin ，但那里没有专门的 java.exe 。我想我从来没有在那里见过 java.exe。

更新6： 看着pathingJar，我加了

grails { pathingJar = true } 

构建.gradle。我不确定我是否也必须创建一个文件？

Answer 1

如果在 Windows 上尝试 ./gradlew bootRun（这解决了我的问题）

Answer 2

您可以尝试两种方法：

在你的 HOME_DIRECTORY 中的 .gradle 目录中的 gradle.properties 中设置 org.gradle.java.home=/path_to_jdk_directory 或：

在你的 build.gradle 中

compileJava.options.fork = true compileJava.options.forkOptions.executable = '/path_to_javac'
