Despite of the fact that you are using Java 1.7 you can compile source code as if you had compiler from Java 1.6 (this can be useful for example for cross-compilation). As Shivam Tiwarisaid in Eclipse you can change it in window->preferences->java->Compiler Compiler
尽管您使用的是 Java 1.7，但您可以像使用 Java 1.6 的编译器一样编译源代码（例如，这对于交叉编译很有用）。正如Shivam Tiwari在 Eclipse 中所说，您可以在 window->preferences->java->Compiler Compiler 中更改它
If you are using Maven you should add the following plugin:
如果您使用 Maven，则应添加以下插件：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>

Maven update with 'Force snapshot release' did the trick. pom.xml doesn't need to be changed.
带有“强制快照发布”的 Maven 更新成功了。pom.xml 不需要更改。
