Question

我想在ClearCase源代码管理下更新文件。这需要从Ant脚本发生。

我已经为此创建了一个快照视图。 ccupdate更新就好了。

我已尝试使用cccheckout，但失败并出现以下错误cleartool: Error: To operate on UCM branch, must be set to an activity and a UCM view.。

有没有办法在快照视图中签出文件，替换它并签入新版本？如果这涉及创建/切换到活动，请在答案中包含此内容。

Answer 1

Apache Ant ClearCase Tasks（2003！）是UCM前的区域这意味着他们没有“UCM视图”（快照或动态）或活动的概念。

如果您要使用ant，您可以尝试（未测试）像clearantlib这样的任务库，它允许您执行任何cleartool命令（使用ccexec）

这样您就可以使用cleartool setact在UCM视图中设置UCM活动只有在设置了活动时，您的结帐才能继续。

Answer 2

由于clearantlib只是一个围绕cleartool命令行的薄包装，因此您可以自己动手。下面是“结帐部分”的一些生产代码片段，这对编写自己的ant任务可能会有所帮助 - 否则您需要使用一堆调用cleartool的ant <exec>部件。在clearcase snapshotview中签出特定版本意味着创建并设置configspec。对于更新部分，请使用ProcessBuilder和相关的cleartool命令：

  /**
   *
   * @param modulinfos
   * @param jobid
   * @param snapshotpath
   */
  private void createConfSpec(ArrayList<String> modulinfos, String jobid, String snapshotpath)
  {
    /*
    element * CHECKEDOUT
    element "/at_vobt2/Foo/.../" v_1_4_00_49a
    element "/at_vobt2/FooBar/.../" v_1_3_02_06c
    element "/at_vobt2/Foo Base/.../" v_1_3_01_28b
    element * /main/LATEST
    load "/vobt2/Foo"
    load "/vobt2/FooBar"
    load "/vobt2/FooBase"
    */

    StringBuilder sb = new StringBuilder("element * CHECKEDOUT");
    for (String string : modulinfos)
    {
      sb.append(nl).append("element \"/" + string.split("#")[0] + "/" + string.split("#")[1] + "/.../\" " + string.split("#")[2]);
    }

    sb.append(nl).append("element * /main/LATEST");

    for (String string : modulinfos)
    {
      sb.append(nl).append("load \"/" + string.split("#")[0] + "/" + string.split("#")[1] + "\"");
    }
    sb.append(nl);

    File file = new File(snapshotpath + "\\" + jobid + ".confspec");
    BufferedWriter writer = null;
    try
    {
      writer = new BufferedWriter(new FileWriter(file));
      writer.write(sb.toString());
      writer.close();
      getLogger().debug("Create ConfigSpec : " + nl + sb.toString() + "File => " + file.getPath());

    isReady = !StringUtils.containsIgnoreCase(sb.toString(), "cleartool: Error: Cannot get view info for current view");
    getLogger().debug("Check Snapshotview : " + snapshotpath + nl + sb.toString());
    return isReady;

如何使用Ant脚本将文件签出/签入ClearCase快照视图？
