解决maven构建eclipse项目中的错误

由于最近把开发环境进行了升级，如svn、eclipse、和maven，都升级到了最新版本。感觉效果很好。但是今天在利用maven构建之前的一个版本的项目时报如下错误：

mvn eclipse:eclipse -e

[INFO] Trace org.apache.maven.lifecycle.LifecycleExecutionException: Request to merge when ‘filtering’ is not identical. Original=resource src/main/resources: output=target/classes, include=[**/*.properties], exclude=[**/*.java], test=false, filtering=true, merging with=resource src/main/resources: output=target/classes, include=[], exclude=[**/*.java], test=false, filtering=false

我查找相关资料，知道是由于升级导致的错误。利用降低maven到2.6即可：

mvn org.apache.maven.plugins:maven-eclipse-plugin:2.6:eclipse

这样就可以成功构建了。

也可以修改pom文件：

<build>
...
  <plugins>
  ...
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-eclipse-plugin</artifactId>
      <version>2.6</version>
    </plugin>
  </plugins>
</build>

这样你利用

mvn eclipse:eclipse也可以构建成功。
