本文介绍了1.3 版不支持 java 泛型和注释(travis 集成)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试将我的 github Java/PHP 项目 与 travis-ci 环境.这是我的 travis 配置:

I'm trying to integrate my github Java/PHP project with travis-ci environment. This is my travis configuration:

language: java
jdk:
  - openjdk7
  - oraclejdk7
script: mvn test

下面是 travis 打印的输出:

Below is the output that travis prints:

输出表明我使用的 Java 版本太旧，无法使用注释和泛型.但这些并不是什么新鲜事，它们必须以某种方式得到支持(我猜).我一直在查看 travis/java 文档，但没有找到关于 java 版本的选项(因此我尝试使用不同的 jdks).谁能指出我应该在 travis 配置文件中放入什么内容?

The output says that I'm using the too old version of java to use annotations and generics. But these are nothing new and they have to be supported somehow (I guess). I've been looking at travis/java docs but found no option about java version (hence I tried to use different jdks). Can anyone point me what should I put into the travis config file?

在@hertzsprung 之后，我运行了 mvn help:effective-pom 并返回了以下输出(实际上，既不是 source 也不是 target 属性是否为 maven-compiler-plugin 定义了注释 - 我该怎么办?):

following @hertzsprung, I ran mvn help:effective-pom and it returned following output (in fact, neither source nor target attribute are note defined for maven-compiler-plugin - what can I do about it?):

推荐答案

请尝试在 pom.xml 中为 Maven 构建配置包含以下代码.我和你有同样的问题，这似乎对我有用:

Please try including the following code in your pom.xml for your Maven build config. I had the same problem as yourself and this seemed to do the trick for me:

<build>
    <pluginManagement>
         <plugins>
             <plugin>
                 <artifactId>maven-compiler-plugin</artifactId>
                 <version>2.3.2</version>
                 <configuration>
                     <source>1.6</source>
                     <target>1.6</target>
                     <compilerArgument></compilerArgument>
                 </configuration>
             </plugin>
         </plugins>
    </pluginManagement>
</build>
