解决svn检出的maven项目clean成功但是compile编译失败问题

maven clean成功，compile失败，抛出错误到控制台：

[INFO] --- maven-compiler-plugin:3.2:compile (default-compile) @ chatserver-persistence ---

以及：



解决：
这是由于项目的jdk使用的版本（jdk1.8）和本地jdk版本(jdk1.7)不一致导致的。
1、修改pom.xml

<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.2</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>

改为：

<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.2</version>
				<configuration>
					<source>1.7</source>
					<target>1.7</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>

2、修改项目的java compiler

项目右击-->properties-->java compiler-->compiler compliance level -->1.7

3、再maven compile,启动正常。
