java - Scout 在启动 SWT 时崩溃

Question

我在 Scout Eclipse 中遇到一些奇怪的错误。我的大学在 git 中推了一些圆锥体，然后我把它拉出来。在他的计算机上一切正常，但在我的计算机上启动 SWT 时出现错误。

错误是:

!ENTRY org.eclipse.e4.ui.workbench 4 0 2014-06-26 09:44:21.234

我真的很努力让它发挥作用，但我已经没有想法了。

Answer 1

== 确保您与同事使用相同的目标平台

打开首选项 > 插件开发 > 目标平台。您应该具有相同的 Activity 目标平台定义。

如果您使用运行平台作为 Activity 目标定义，您应该具有完全相同的 Eclipse IDE 安装以便能够进行比较。

== 确保以相同的方式启动应用程序

打开客户端产品文件例如:

/<your-app>.ui.swt/products/development/<app>-swt-client-dev.product

单击概述选项卡测试部分中的同步链接。 (有时您需要执行两次此操作)。

使用同一部分中的运行或调试按钮启动应用程序。

== 在您的计算机上测试其他侦察应用程序

要确定您的 eclipse scout IDE 安装是否正常，当您在其他工作区中创建测试应用程序时发生了什么？你能启动它吗？

==验证您的目标平台的内容

@marko-zadravec 建议验证您是否没有 org.eclipse.jface 的 2 个版本在您的目标平台中。

在“目标平台”首选项页面中，在列表中选择 Activity 目标定义，然后单击编辑按钮。

切换到内容标签。检查你是否没有两个org.eclipse.jface捆绑。

==重新安装 IDE

有时重新安装 Eclipse for Scout Developers 是解决此类问题的最快解决方案(转到 Eclipse Downloads 页面)。
