为什么我的 java 程序无法加载 maven 插件？

Question

我正在处理 JAVAFX application，我正在使用 pom.xml 文件，我在其中有依赖项，它在我上一台电脑上运行良好，但是当我将它导入另一台电脑时它给我一个错误，未能执行 maven plugin，我已经在互联网上搜索，并遵循所有可能的解决方案，但都对我不起作用。

现在我有一个问题，为什么我会收到加载 maven 插件失败的错误消息？

这是日志跟踪：

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project EmployeeManagement: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

For more information about the errors and possible solutions, please read the following articles:

这是我的 pom.xml

Answer 1

exec 插件执行路径 ${java.home}/../bin/javapackager.

中的二进制文件

执行它时 returns 错误代码为 1，这很可能是它找不到二进制文件。

检查您是否拥有有效的 JAVA_HOME 并且 javapackager 存在。也许你在新机器上有jre？

Answer 2

我已经解决了这个问题，实际上它抛出了一个错误 failed to execute 因为我的代码中有一些其他的构建错误，这些错误与 MySQL 相关，在此之前我认为让我首先解决此 plugin 错误，然后我会删除该错误，但是当我没有得到任何合适的答案时，我想删除其他错误，然后我会回到这里并删除该错误，但是当我删除其他错误时，奇迹发生了，所有错误都消失了，MySQL 以及 plugin 错误。

不知道为什么，但它对我有用。不知道为什么把其他错误去掉，把这个问题也去掉了，这之间有什么关系。
