找不到Maven Dependencies

我的maven项目找不到Maven Dependencies，经过多种尝试和各种网上解决方法摧残，最后我配置了：

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-resources-plugin</artifactId>

<version>2.4.3</version>

<configuration>

<encoding>${project.build.sourceEncoding}</encoding>

</configuration>

</plugin>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>2.0.2</version>

<configuration>

<source>1.6</source>

<target>1.6</target>

<encoding>${project.build.sourceEncoding}</encoding>

</configuration>

</plugin>

</plugins>

然后在maven->update project 最后就出现Maven Dependencies。
