我正在尝试将我的github Java / PHP项目与travis-ci环境集成。这是我的travis配置：
language: java jdk: - openjdk7 - oraclejdk7 script: mvn test
下面是travis打印的输出：

输出显示我使用的Java版本太旧，无法使用注释和泛型。但是这些并不是什么新鲜事物，它们必须以某种方式得到支持（我想）。我一直在查看travis / java文档，但没有找到有关Java版本的选项（因此我尝试使用其他jdks）。谁能指出我该在travis配置文件中放什么？
编辑：
在@hertzsprung之后，我运行mvn help:effective- pom并返回以下输出（实际上，注释source和target属性均未定义maven-compiler-plugin-我该怎么办？）：
mvn help:effective- pom
source
target
maven-compiler-plugin

这是我的原始pom.xml内容：
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.blogspot.symfony-world</groupId> <artifactId>wealthy-laughing-duck</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>wealthy-laughing-duck</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.thrift</groupId> <artifactId>libthrift</artifactId> <version>0.9.0</version> </dependency> <dependency> <artifactId>slf4j-api</artifactId> <groupId>org.slf4j</groupId> <type>jar</type> <version>1.7.3</version> </dependency> <dependency> <artifactId>hibernate-core</artifactId> <groupId>org.hibernate</groupId> <type>jar</type> <version>4.1.10.Final</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.24</version> </dependency> </dependencies> </project>
请尝试在pom.xml中为Maven构建配置包含以下代码。我和自己有同样的问题，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>
