Eclipse E4:可怕的 Eclipse/OSGI 核心 NullPointerException(等)在启动时终止应用程序
Eclipse E4: Awful Eclipse/OSGI core NullPointerException (etc.) that is terminating app on startup
定期 运行-ning 测试 E4 应用程序(通过 Eclipse IDE)没有太多问题。但是,我刚刚在启动时遇到一个错误 (RUN/DEBUG),它会在应用程序启动之前终止它。它在任何 window 显示之前就死了。我不知道为什么会这样。IDE
通过 DEBUG,我遇到的第一个错误 (NullPointerException) 在:
org.eclipse.core.internal.resources.CharsetDeltaJob class: at line 206 (the Platform. call):
public void startup() {
Platform.getContentTypeManager().addContentTypeChangeListener(this);
}
我还在终端或日志中收到大量错误消息。我找不到对我的任何代码的引用。这一切似乎都是 Eclipse 的核心内容。我将把它们包括在这条消息的末尾。问题:
1) 有什么方法可以确保 OSGi 系统在新的 DEBUG/RUN 调用时完全重启?
2) 这是"deep"的常见错误吗?
3) 调试这类东西有什么建议吗?我在 Eclipse/E4 上取得了一些成功,但如果这种级别的错误很常见,我不确定我是否能够继续。

纯 e4 应用程序(使用 Application.e4xmi 的应用程序)不能使用很多旧的 Eclipse 3.x 兼容性代码。在这种情况下,您似乎包含了 org.eclipse.core.resources
插件(或者 Eclipse 可能错误地自动添加了它们)。
在使用 xxx.product 文件构建 RCP 时,如果您使用 'feature based' 构建,您只需指定功能:
<your feature>
org.eclipse.e4.rcp
org.eclipse.emf.common
org.eclipse.emf.core
这将确保构建仅使用 e4 插件。
可以使用其他一些Eclipse插件,例如:
org.eclipse.jface.text
org.eclipse.text
基本上你必须查看插件的依赖关系,看看是否使用了无法正常工作的插件,例如 org.eclipse.core.resources
或任何 org.eclipse.ui.*
插件。
我在构建最小的捆绑包集以使用 org.eclipse.jdt.core.JavaCodeFormatter
Eclipse 应用程序时遇到了同样的问题。当org.eclipse.core.runtime.content.IContentTypeManager
服务不可用时Platform.getContentTypeManager()
导致NPE。
确保您拥有以下捆绑包:
osgi.bundles=\
org.apache.felix.scr@2:start,\
org.eclipse.core.runtime@start,\
org.eclipse.core.contenttype
# other bundle dependencies
Apache Felix SCR 包必须在运行级别 2 启动,以便 Eclipse 内容机制可以注册其服务,这是核心资源管理包所需要的。
定期 运行-ning 测试 E4 应用程序(通过 Eclipse IDE)没有太多问题。但是,我刚刚在启动时遇到一个错误 (RUN/DEBUG),它会在应用程序启动之前终止它。它在任何 window 显示之前就死了。我不知道为什么会这样。IDE
通过 DEBUG,我遇到的第一个错误 (NullPointerException) 在:
org.eclipse.core.internal.resources.CharsetDeltaJob class: at line 206 (the Platform. call):
public void startup() {
Platform.getContentTypeManager().addContentTypeChangeListener(this);
}
我还在终端或日志中收到大量错误消息。我找不到对我的任何代码的引用。这一切似乎都是 Eclipse 的核心内容。我将把它们包括在这条消息的末尾。问题:
1) 有什么方法可以确保 OSGi 系统在新的 DEBUG/RUN 调用时完全重启?
2) 这是"deep"的常见错误吗?
3) 调试这类东西有什么建议吗?我在 Eclipse/E4 上取得了一些成功,但如果这种级别的错误很常见,我不确定我是否能够继续。

纯 e4 应用程序(使用 Application.e4xmi 的应用程序)不能使用很多旧的 Eclipse 3.x 兼容性代码。在这种情况下,您似乎包含了 org.eclipse.core.resources
插件(或者 Eclipse 可能错误地自动添加了它们)。
在使用 xxx.product 文件构建 RCP 时,如果您使用 'feature based' 构建,您只需指定功能:
<your feature>
org.eclipse.e4.rcp
org.eclipse.emf.common
org.eclipse.emf.core
这将确保构建仅使用 e4 插件。
可以使用其他一些Eclipse插件,例如:
org.eclipse.jface.text
org.eclipse.text
基本上你必须查看插件的依赖关系,看看是否使用了无法正常工作的插件,例如 org.eclipse.core.resources
或任何 org.eclipse.ui.*
插件。
我在构建最小的捆绑包集以使用 org.eclipse.jdt.core.JavaCodeFormatter
Eclipse 应用程序时遇到了同样的问题。当org.eclipse.core.runtime.content.IContentTypeManager
服务不可用时Platform.getContentTypeManager()
导致NPE。
确保您拥有以下捆绑包:
osgi.bundles=\
org.apache.felix.scr@2:start,\
org.eclipse.core.runtime@start,\
org.eclipse.core.contenttype
# other bundle dependencies
Apache Felix SCR 包必须在运行级别 2 启动,以便 Eclipse 内容机制可以注册其服务,这是核心资源管理包所需要的。
