Maven - 为什么在“mvn clean”之后我需要执行“Maven更新项目”之前的“mvn包”？ [英] Maven - Why after "mvn clean" I need to execute "Maven Update Project" before "mvn package"?

问题描述

我正在进行一些测试，我想了解为什么执行命令 mvn clean 我需要执行Maven>更新项目，然后运行 mvn package ，否则我在包装中的一个依赖关系中收到编译错误。

在运行Maven>更新项目之前，我的项目看起来不能正确编译我的项目，但我不确定。
这是正常吗？

• 我正在使用Eclipse，并通过mvn clean和{mvn package}运行为> Maven Build。

这是我的pom.xml：

解决方案

发生这种情况：

1. mvn clean 删除目标目录


2. mvn package 执行一些工作，但是由于缺少依赖关系，因此遇到编译错误。这就是为什么目标文件夹出错。


3. 在Eclipse中运行Maven> Update Project会使Eclipse执行自己的编译，与Maven分开。 Eclipse具有与Maven不同的类路径，因此它的编译成功。现在，目标目录具有所有编译的类。


4. 重新运行 mvn package 现在成功，因为它发现所有的类都已经编译完成，不需要执行任何编译。

最终，问题在 pom.xml 中的项目配置中。我有同样的问题，在添加缺少的依赖项后，我用Maven成功编译了项目。

I'm making some tests and I would like to understand why after execute the command mvn clean I need to execute "Maven > Update Project" before run mvn package, otherwise I get a compilation error in one of my dependencies during the packaging.

It looks like my project doesn't compile correctly my project before running "Maven > Update Project", but I'm not sure. Is this normal?

• I'm using Eclipse and run the commands {mvn clean} and {mvn package} via "Run as > Maven Build".

Here is my pom.xml:

解决方案

Here is what happens:

1. mvn clean deletes the target directory
2. mvn package performs some work, but then encounters a compilation error due to a missing dependency. That's why the target folder is in error.
3. Running Maven > Update Project in Eclipse causes Eclipse to perform its own compilation, separate from Maven. Eclipse has a different classpath than Maven, so its compilation succeeds. Now the target directory has all the compiled classes.
4. Re-running mvn package now succeeds, because it finds all the classes already compiled and doesn't need to perform any compilation.

Ultimately, the problem is in the project configuration in pom.xml. I had the same problem, and after adding the missing dependency I successfully compiled project with Maven.

这篇关于Maven - 为什么在“mvn clean”之后我需要执行“Maven更新项目”之前的“mvn包”？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
