Eclipse 无法启动调试为

【问题标题】：Eclipse cannot start Debug AsEclipse 无法启动调试为
【发布时间】：2010-12-17 15:21:16
【问题描述】：

我正在 Eclipse 中处理 Java 项目。我可以启动应用程序（运行方式）并且工作正常，但我无法启动调试方式（我可以启动调试方式但突然我不能了）。有人对这种奇怪的东西有经验吗？

  • 那么，除了调试器在您的第一个断点处停止，您返回或看到了什么？

标签： java eclipse debugging stack-trace


【解决方案1】：

我看到这两个菜单分别对它们的目标感到困惑。例如，对于 Ant 构建文件，一个将继续命名为“Run As>Ant Build”，另一个将命名为其他内容，并且失败。

重启Eclipse总能解决问题。

    【解决方案2】：

    根据确实应该成为问题一部分的（格式错误的）答案，看起来您的套接字地址可能格式错误。

    就 INetAddress.getLocalhost 而言，NumberFormatException 一遍又一遍地重复...

    啊！你有 IPv4 还是 IPv6？如果 v4（十进制）解释器试图解析 v6（十六进制）地址，事情可能会被破坏。

    也可能是您的调试套接字编号不是数字（至少不是十进制数字）...但我在 UI 中看不到任何地方可以调整它，所以我看不出您如何把它弄坏了。

    【讨论】：

      【解决方案3】：

      只是为了将来有人会遇到同样的问题。最近我被同一个用例（但在 NetBeans 中）愚弄了 - 问题是由我前段时间创建的 java.lang.IllegalArgumentException 上的断点引起的，但后来忘记了，所以 IDE 一直在某个地方停止Java核心代码只是因为那个断点，但我认为它是由我的代码或运行时环境中的某些东西引起的:(

      实际上，我会说这个问题是核心 Java 库中的一般编码风格。在 if() 条件更合适的情况下，有很多地方会引发异常，这会导致异常调试的主要问题——它们太多了。在这种特殊情况下，问题是由以下几行引起的（我从这里 http://download.java.net/openjdk/jdk6/ 获取了 InetAddressCachePolicy 的来源）：

          try {
        tmp = new Integer(
          java.security.AccessController.doPrivileged (
            new PrivilegedAction<String>() {
              public String run() {
                  return Security.getProperty(cachePolicyProp);
              }
          }));
    } catch (NumberFormatException e) {
        // ignore
    }

      您可能会注意到编写代码的人知道配置中提供的潜在“非数字”字符串，但没有尝试更优雅地处理至少字符串为空或空的情况，这实际上是这个问题的案例。

      这里有关于 Integer.parseInt() 的相关讨论 - Java: Good way to encapsulate Integer.parseInt()
