創建Maven項目時遇到的警報：Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment.
通過右鍵項目—》add Plugin添加，填入org.apache.maven.plugins，選擇maven-compiler-plugin，POM文件自動生成，
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
然後更新Maven的Project。
