java - "The application could not start"运行插件时会产生堆栈跟踪，但不会产生调试 session

Question

我正在修复一个旧的 Eclipse 插件，以便它在 Neon 中运行。我设法按照 https://sourceforge.net/p/e-p-i-c/discussion/258688/thread/7475efd7/#f9cc/cc8a 通过 File->Import... 导入依赖项，修复了所有剩余的编译错误，现在准备尝试一下。

但是，当我调试为...“Eclipse 应用程序”或“OSGi 框架”时，它会显示“应用程序无法启动”错误对话框，然后根据我的情况选择几个堆栈跟踪。

但这没有用。 我需要进行调试 session ，以便我可以检查变量并尝试推断出问题所在(因为我不熟悉常见的 Eclipse 插件堆栈跟踪，无法说出这个特定的问题意味着只是通过查看它)。

乍一看，设置看起来不错:

• 子进程通过命令行启动"C:\Program Files\Java\jre1.8.0_121\bin\javaw.exe"-agentlib:jdwp=transport=dt_socket,suspend=y,地址=本地主机:50467 -Declipse.pde.launch=true -Dfile.encoding=UTF-8 -classpath "C:\Users\Ivan\.p2\pool\plugins\org.eclipse.equinox.launcher_1.3.201.v20161025- 1711.jar"org.eclipse.equinox.launcher.Main -launcher "C:\Users\Ivan\eclipse\committers-neon\eclipse\eclipse.exe"-name Eclipse -showsplash 600 -product org.eclipse.platform.ide -data "C:\Users\Ivan\workspace-antlr/../runtime-New_configuration"-配置文件:C:/Users/Ivan/workspace-antlr/.metadata/.plugins/org.eclipse.pde.core/New_configuration/-dev 文件:C:/Users/Ivan/workspace-antlr/.metadata/.plugins/org.eclipse.pde.core/New_configuration/dev.properties -os win32 -ws win32 -arch x86_64 -nl en_US -consoleLog 看起来不错(“New_configuration”启动配置的类型为“Eclipse Application”)。

• The "suspend on uncaught exceptions" flag已设置。

我主要对如何进入调试器感兴趣。如果您只是帮我解决这个特定错误，我很可能会立即遇到另一个错误。

Answer 1

看起来这可能是 this Oomph 安装程序代码中的 Eclipse 错误。该错误被标记为已修复并已关闭，但尚不清楚它位于哪个 Eclipse 版本中(可能是即将发布的 4.6.3)。

一种可能的解决方法是使用基于不使用 Oomph 的较简单 Eclipse 安装之一的目标平台。这些可以找到here 。
