默认eclipse建立maven项目时，JDK版本往往是1.5

如果你用eclipse建立maven项目时，新建的项目往往JDK版本很低——1.5！怎么办？修改settings.xml文件，增加profile节点，如下所示：

 <profile>  
		<id>jdk-1.6</id>  
		<activation>  
			<activeByDefault>true</activeByDefault>  
			<jdk>1.6</jdk>  
		</activation>  
		<properties>  
			<maven.compiler.source>1.6</maven.compiler.source>  
			<maven.compiler.target>1.6</maven.compiler.target>  
			<maven.compiler.compilerVersion>1.6</maven.compiler.compilerVersion>  
		</properties>  
	</profile>

完整settings.xml文件配置如下：

<?xml version="1.0"?>
<settings>
	<mirrors>
		<mirror>
			<id>nexus</id>
			<name>local private nexus</name>			
			<url>http://10.10.10.149:8081/nexus/content/groups/public</url>

	<profile>

		<activation>  
			<activeByDefault>true</activeByDefault>  
			<jdk>1.6</jdk>  
		</activation>  
		<properties>  
			<maven.compiler.source>1.6</maven.compiler.source>  
			<maven.compiler.target>1.6</maven.compiler.target>  
			<maven.compiler.compilerVersion>1.6</maven.compiler.compilerVersion>  
		</properties>  
	</profile>
	
</settings>

pom中加插件即可

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
	<version>3.0</version>
	<configuration>
		<target>1.6</target>
		<source>1.6</source>
		<encoding>UTF-8</encoding>
	</configuration>
</plugin>
