3.4.2.6 构建前操作

3.4.2.7 项目发布

3.4.2.8 项目验证

四、注意要点

4.1 运行权限问题

yum安装的Jenkins 配置文件默认位置/etc/sysconfig/jenkins

默认jenkins服务以jenkins用户运行，这时在jenkins执行maven脚本时可能会发生没有权限操作某个目录下的文件，覆盖文件等情况。例如可能会报下面的错误。

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.5.2:install (default-install) on project icps-parent: Failed to install artifact io.binghe:binghe-parent:pom:1.0.0-SNAPSHOT: /home/repository/io/binghe/binghe-parent/1.0.0-SNAPSHOT/binghe-parent-1.0.0-SNAPSHOT.pom (权限不够) -> [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.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

可以让jenkins以root用户运行来解决这个问题

1. 将jenkins账号分别加入到root组中

gpasswd -a jenkins root
1

2. 修改/etc/sysconfig/jenkins文件中

#user id to be invoked as (otherwise will run as root; not wise!)
JENKINS_USER=root
JENKINS_GROUP=root
1

3

可以修改为root权限运行
重启服务，搞定。

4.2 部署项目报错

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

报错的大致意思是：

不能从配置的Git仓库中找到pom.xml文件。

查看Jenkins工作空间下是否有pom.xml文件。

发现我的工作空间下没有pom.xml文件，我的pom.xml文件在code目录下。但是Jenkins配置时候默认是找工作空间下的pom.xml。

解决方案：修改Jenkins查找pom.xml文件的路径。

重新构建即可。
