Jenkins将不使用Java 7编译器

问题描述

我正在与一个团队一起进行maven项目，并在Jenkins中为其建立了构建工作.

I'm working with a team on a maven project, and I set up a build job for it in Jenkins.

最近，团队中的某人添加了在字符串上切换的代码.这导致在Jenkins中构建失败，并出现以下错误:

Recently, someone on the team added code that switches on a String. This caused the build to fail in Jenkins with the following error:

error: strings in switch are not supported in -source 1.5

因此，我当然意识到Jenkins需要使用Java 7，而不是Java 5.

So of course I realized Jenkins needs to be using Java 7, not Java 5.

首先，我远程进入服务器，打开一个cmd，然后执行where java和java -version.我检查了我的环境变量和路径.一切都指向相同的Java 7 jdk目录:C:\Java\jdk1.7.0_21.

First, I remoted into the server, opened a cmd, and did where java and java -version. I checked my environment variables and my path. Everything is pointing to the same Java 7 jdk directory: C:\Java\jdk1.7.0_21.

然后，我检查了Jenkins，以查看它是否配置为使用正确的JDK.它是:

Then I checked Jenkins to see if it was configured to use the correct JDK. It is:

实际上，这是Jenkins服务器设置为使用的唯一Java，并且是服务器中安装的唯一Java.

In fact, that's the only Java that the Jenkins server is set up to use, and it's the only Java installed in the Server.

作为最后的选择，我将JDK参数插件安装到Jenkins中.然后，我将项目设置为使用Java 7参数:

As a last resort, I installed the JDK parameter plugin into Jenkins. I then set the project to use the Java 7 parameter:

但是，我仍然遇到相同的错误.

But still, I get the same error.

我错过了什么吗?是什么原因造成的?最重要的是，我该如何解决它并使Jenkins使用-source 1.7而不是-source 1.5?

Am I missing something? What could be causing this? Most importantly, how can I solve it and get Jenkins to use -source 1.7 instead of -source 1.5?

推荐答案

检查pom.xml以及在那里指定的Java版本(用于源代码).可能是source 1.5的来源.

Check your pom.xml and what java version (for the source) is specified there. That could be where the source 1.5 is coming from.

<properties>
   <jee.level>1.4</jee.level>
   <jdk.level>1.5</jdk.level>
</properties>

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <configuration>
       <source>${jdk.level}</source>
       <target>${jdk.level}</target>
   </configuration>
</plugin>
