java - 1.3 版不支持 java 泛型和注解（travis 集成）

Question

我正在尝试将我的github Java/PHP 项目与travis-ci环境集成。这是我的特拉维斯配置：

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

下面是 travis 打印的输出：

输出表明我使用的是太旧的 java 版本，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 配置文件中添加什么？

编辑：

在@hertzsprung 之后，我运行mvn help:effective-pom并返回了以下输出（事实上，既source没有target定义注释也没有定义属性maven-compiler-plugin- 我该怎么办？）：

请尝试在您的 pom.xml 中为您的 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：

<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>

看起来出于某种奇怪的原因，travis 使用源级别和目标 jvm 设置为 jdk 1.3。我认为他们应该保持 maven 默认值（即 1.5），因为这个错误让我感到意外，并且花了一些时间来修复它，因为我不想根据外部工具更改我的项目配置和行为。

如果你想避免修改你的 pom.xml（它不应该依赖于你的持续集成工具），你可以将 travis 配置为使用适当的源级别和目标 jvm 进行编译：

language: java
jdk:
  - oraclejdk7
  - openjdk7
install: mvn install -Dmaven.compiler.target=1.5 -Dmaven.compiler.source=1.5 -DskipTests=true -B
script: mvn test -Dmaven.compiler.target=1.5 -Dmaven.compiler.source=1.5 -B

这将使用 1.5 源代码级别进行编译并生成针对 1.5 jvm 的字节码。如果要定位 1.7，可以指定 1.7 代替 1.5。

java - 1.3 版不支持 java 泛型和注解（travis 集成）
