发布时詹金斯上的Maven编译失败：执行答案

【问题标题】：maven compilation failure on jenkins while release:perform发布时詹金斯上的Maven编译失败：执行
【发布时间】：2018-01-23 18:26:17
【问题描述】：

我在 Jenkins 上有一份工作，我想向 Nexus 发布一个工件。它在执行期间抱怨 mavne-compiler-plugin 和 maven-release-plugin。关于问题是什么以及如何解决它的任何想法？

在 Jenkins 工作中，我还检查了 Delete workspace before build starts 并添加了 Check out to specific local branch 设置为 'master'

这是maven命令

mvn release:clean release:prepare release:perform -DreleaseVersion=${releaseVersion} -DdevelopmentVersion=${developmentVersion} -X

错误看起来像这样

【解决方案1】：

该错误是由 maven-compiler-plugin 引发的，因此它与编译有关。实际上，该错误是由于代码中的“未找到符号”而导致的简单编译错误。

您应该将此依赖项添加到您的 pom：

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
</dependency>

对于这个特定的库，最好也使用scope=provided 进行设置。
