svn1.7 appears to be part of a Subversion 1.7 or greater working copy. Please upgrade your Subversio

The current (8.0-SNAPSHOT) build uses version 1.5 of the maven-svn-revision-number-plugin plugin, when source code has been checked out using a subversion client version 1.7 the build fails with a subversion error because the repository metadata in the working
copy is not upward compatible, 

com.google.code.maven-svn-revision-number-plugin:1.5:maven-svn-revision-number-plugin uses SVNkit 1.3.x which is compatible with subversion 1.6=<

When the maven-svn-revision-number-plugin is updated to version 1.7 (currently latest release of this plugin) you can specify a commandline option (-Dsvn-revision-number.failOnError=false) to ignore the subversion error and the build completes normally. Note
that com.google.code.maven-svn-revision-number-plugin:1.7:maven-svn-revision-number-plugin still relies on svnkit:1.3.5 so the error is still there, the updated plugin just gives an option to ignore it either from the commandline or as a config option.

出现了这样的错误的时候 是svn版本问题 

由于我的电脑上安装了客户端是1.7的版本 

但是pom.xml中使用的是1.6

   <plugin>

    <groupId>com.google.code.maven-svn-revision-number-plugin</groupId>

    <artifactId>maven-svn-revision-number-plugin</artifactId>

    <version>1.6</version>

    <executions>

     <execution>

      <goals>

       <goal>revision</goal>

      </goals>

     </execution>

    </executions>

    <configuration>

     <entries>

      <entry>

       <prefix>SVN</prefix>

      </entry>

     </entries>

    </configuration>

   </plugin>

在编绎时  出现了上述异常 ，我想可能是版本问题 于是乎我就把pom.xml中maven-svn-revision-number-plugin的<version>1.6</version>改成了<version>1.7</version>

心想可能问题解决了 没想到编绎时还是报以上错误 

于是在网上狂搜 终于发现了 有人也出现了这样的问题 

经过实验发现这个方案靠谱 就记录下来了 路过的人看到了也可以方便解决问题

方案：

     当然上面的<version>1.7</version>还是要保留的 因为我的客户端也是1.7

然后呢  在编绎的时候  要加入 -Dsvn-revision-number.failOnError=false

来个完整的 命令：eclipse:eclipse -Dsvn-revision-number.failOnError=false

就这样ok了。
