我也有遇到這種情況，右鍵項目-->properties-->java compile， 將里面的默認的1.5改成你的jdk版本，OK

pm.xml里加入下面這一行試試。
?<profiles>
??<profile>
???<id>jdk-1.8</id>
???<activation>
????<activeByDefault>true</activeByDefault>
????<jdk>1.8</jdk>
???</activation>
???<properties>
????<maven.compiler.source>1.8</maven.compiler.source>
????<maven.compiler.target>1.8</maven.compiler.target>
????<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
???</properties>
??</profile>

1，可以用maven clean命令clean一下，然后項目在maven上選擇update project；
2，可以選擇navigator模式查看，或者查看隱藏文件里的JAVA編譯模式。
3，再不行重新啟動eclipse。
