用于Maven进行条件检出或从SVN更新的设置? [英] Settings for Maven for conditional checkout or update from SVN?

问题描述

我在POM文件中有以下设置.但是我的构建脚本失败并显示``SVN文件已锁定''消息.是否还有其他方法可以进行条件检出.如果项目已检出，则仅在项目为没有签出，应该签出代码，并且不应该更新代码.谢谢.

I have following settings in POM file.But my build script fails with 'SVN file locked' message.Is there any other way to do conditional checkout.If project is already checked out then I want to update only otherwise if project is not checkedout it should check out the code and should not update it.Thanks in advance.

      <!-- Initial check out of  (will not do anything if directory already there) -->
      <execution>
        <id>check-out-project</id>
        <phase>generate-sources</phase>
        <goals>
          <goal>checkout</goal>
        </goals>
        <configuration>
          <checkoutDirectory>${project.build.directory}/project</checkoutDirectory>
          <connectionUrl>scm:svn:http://XX:XX/svn/repos/${XX}</connectionUrl>
          <username>${svn.username}</username>
          <password>${svn.password}</password>
          <skipCheckoutIfExists>true</skipCheckoutIfExists>
        </configuration>
      </execution>
      <!-- Update project (if directory was already there) -->
      <execution>
        <id>update-project</id>
        <phase>generate-sources</phase>
        <goals>
          <goal>update</goal>
        </goals>
        <configuration>
          <basedir>${project.build.directory}/project</basedir>
          <connectionUrl>scm:svn:http://XXX:XXX/svn/repos/${project}</connectionUrl>
          <username>${svn.username}</username>
          <password>${svn.password}</password>
          <revisionKey>project.revision</revisionKey>
        </configuration>
      </execution>
