Maven 3 Jenkins插件——Hello World示例的“构建失败”

Question

我是第一次使用Jenkins/Maven，并遵循这两个教程编写Jenkins插件：https://wiki.jenkins-ci.org/display/JENKINS/Plugin教程和http://cleantestcode.wordpress.com/2013/11/03/how-to-write-a-jenkins-plugin-part-1/.

到目前为止，我在Windows上的提示下输入了以下命令/数据：

1. mvn hpi：创建-Pjenkins

步骤5的结果是“BUILD FAILURE”，输出如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.9:test           (default-test) on project hello_world: There are test failures. [ERROR] 
[ERROR] Please refer to C:\$HOME\hello_world\target\surefire-reports for the individual test results. [ERROR] -> [Help 1] [ERROR]  
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging.

我尝试了“mvn install-DskipTests”，但这样（我不知道该如何表达）命令提示符就再也不会出现，我无法输入更多的命令。

我的问题如下：

1. 我没有修改“mvn hpi：create-Pjenkins”生成的任何文件，那么是什么导致默认测试失败呢
2. 如果没有“-Pjenkins”标志，“mvn hpi:create”命令也会导致构建失败。添加“-Pjenkins”标志的效果如何

提前感谢任何答案。

Answer 1

尝试跳过测试，将第5个命令更改为：5。mvn安装-DskipTests
