Maven不会打包java项目

我正在尝试制作一个.jar的java maven项目。该项目本身是一个helloworld项目，所以我不会发布实际的java代码。项目名称是测试这里的测试/ pom.xml中：Maven不会打包java项目

道歉坏的格式，我能格式化XML没有任何问题，但错误跟踪不会让步。有关于此的任何提示？ – Serge

要格式化控制台输出，您只需在控制台输出和之前的行之间添加空行。 – DB5

好了，我想通了，我什么特别问题是，但我会认为我以前的方法也应该起作用。

我在项目文件夹之外运行命令（在这种情况下是'test'）。一旦我在文件夹内导航并运行mvn包，它会在目标文件夹中生成.jar。

以前我是试图将项目传递给包命令以这种方式：

mvn package test

哪一个不行。 'mvn package test'会尝试首先运行该程序包，然后再次进入测试阶段。（假设test是项目名称）会是：'mvn package -f test/pom.xml' – blackbuild
