目标的执行 delombok org.projectlombok:lombok-maven-plugin:1.16.10.0:delombok 失败：执行 org.projectl 时缺少必需的 class
Execution delombok of goal org.projectlombok:lombok-maven-plugin:1.16.10.0:delombok failed: A required class was missing while executing org.projectl
我正在开发 Lombok 和 运行 来自 link 的应用程序：https://github.com/eugenp/tutorials/tree/master/lombok 尚未对该代码进行任何修改。
当我使用 > mvn clean install -DskipTests 简单地构建代码时，出现以下错误，同样的 STS 也显示相同的问题是什么？
以下错误供参考？

我刚得到这个问题的解决方案如下所述。
1.下载龙目岛 Jar 文件 -
最好在你的应用程序中有一个 Maven/Gradle 依赖。可以在此处找到 Maven 依赖项：https://mvnrepository.com/artifact/org.projectlombok/lombok
2。开始安装Lombok -
在本地存储库中下载 jar 后，从命令提示符转到 jar 位置，然后 运行 以下命令 java -jar lombok-1.16.18.jar 我们应该会看到 lombok 提供的 Lombok 安装 window 像这样。
3。提供 Lombok 安装路径 - 现在单击 “Specify Location” 按钮并找到 eclipse 安装文件夹下的 eclipse.exe/STS.exe 路径，如下所示。
4.完成 Lombok 安装 - 现在我们需要通过单击 “Install/Update” 按钮来最终安装它，我们应该在 eclipse 中完成 lombok 的安装，我们准备好使用它隐藏的力量。最终屏幕看起来像，
5.请确保将以下条目添加到 STS.ini 文件中，如果它不存在的话。
-vmargs -javaagent:lombok.jar
注意：完成所有这些操作后，如果这不起作用，请确保更改工作区并重新构建代码。它会起作用。
我正在开发 Lombok 和 运行 来自 link 的应用程序：https://github.com/eugenp/tutorials/tree/master/lombok 尚未对该代码进行任何修改。
