Maven和Spark，Java执行的错误消息

我使用Eclipse运行我的Spark代码并在Eclipse中使用工具Maven构建依赖关系。目前我有这种情况，当我不得不从Eclipse平台，而是从控制台（bash）运行我的代码。我上传并在本地机器上安装Maven，并使用不同的简单示例进行播放。我的Maven文件夹位于Downloads库中。所有的标准例子都很好，我有一个正确的输出。我在this site上找到的所有介绍。现在我想要执行一个spark代码。将我的Java文件放入目录中的Spark代码后，在其中有其他文件，并更新了pom.xml后，我无法构建我的jar文件。我得到了下一个错误：Maven和Spark，Java执行的错误消息

我怎么理解，是我的Spark版本的所有错误。我目前使用spark 1.4.0版本。我还张贴我的pom.xml文件：

关于在错误信息底部的链接的文件是不是行家的错误，but something wrong is with plugin.

你需要设置你的java编译器versnion，它似乎你的maven正在尝试使用java 1.3 – eliasah

这很奇怪，maven通常使用$ JAVA_HOME设置的版本，并且在这种情况下我有Java8 ... – Guforu

我只是告诉你你的错误日志说什么。 – eliasah

根据你的错误日志，您需要将maven中的java编译器版本设置为相应的Java版本（1.7或1.8）。看来你的Maven是使用旧版本的Java（1.3）

<properties> 
    <maven.compiler.source>1.8</maven.compiler.source> 
    <maven.compiler.target>1.8</maven.compiler.target> 
</properties>

这是放弃了错误的行：

spark-1.4.0-bin-hadoop2.6/apache-maven-3.3.3/my-app/src/main/java/app/SimpleApp.java:[12,11] error: generics are not supported in -source 1.3
