每周周一的时候，bamboo最容易出问题。因为我这边bamboo是server – agent的模式 ———— server端在公网，根据项目的不同分配了多个agent端在本地。每周到公司遇到的最多的问题就是agent端的机器因断电等需要重新连接server端 。不过上周一遇到另外一个情况，问题出在server端。bamboo打包时报错内容如下：

<pre class="prettyprint lang-xml">re-install the plugin with key "com.atlassian.bamboo.plugins.maven:task.builder.mvn3"

详见下面的截图：

之前一直是好，所以mvn插件肯定是装好的。网上查了下解决方法 ，其中在atlsattian的anwsers中发现这样一个链接https://answers.atlassian.com/questions/206697/bamboo-5-1-maven-missing ，其中提到：

<pre class="prettyprint lang-xml">Aha! Found it, somehow, the maven plugin had gotten disabled. I didn't find it before because I didn't realize you have to switch the pulldown from "user plugins" to "system plugins" before I could find it greyed out in the list and re-enable it.

需要在user plugins的下拉菜单中找到system plugins，然后启用mvn插件就行了。

注：记得点开show system add-ons才可以查看所有的插件 。
