使用maven开发过程中，pom报的一些错的解决方法

1.  maven-resources-plugin prior to 2.4 is not supported by m2e. Use maven-  resources-plugin versio

在项目的pom.xml文件中插入以下代码即可：

<build>
        <plugins>  
          <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.5</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins> 
    </build>

2.maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.

<pluginManagement>
              <plugins>
              <!-- Ignore/Execute plugin execution -->
               <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                 <lifecycleMappingMetadata>
                  <pluginExecutions>
                   <pluginExecution>
                    <pluginExecutionFilter>
                     <groupId>org.apache.maven.plugins</groupId>
                     <artifactId>maven-dependency-plugin</artifactId>
                     <versionRange>[1.0.0,)</versionRange>
                     <goals>
                      <goal>copy-dependencies</goal>
                      <goal>unpack</goal>
                     </goals>
                    </pluginExecutionFilter>
                    <action>
                     <ignore />
                    </action>
                   </pluginExecution>
                  </pluginExecutions>
                 </lifecycleMappingMetadata>
                </configuration>
               </plugin>
              </plugins>
          </pluginManagement>

3. Can not find the tag library descriptor for "http://www.springframework.org/security/tags"

<dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-taglibs</artifactId>
            <version>3.0.2.RELEASE</version>
        </dependency>
