我有一个应用程序，我想将其导出为产品。为此，我为我的RCP应用程序创建了一个产品。在创建产品定义时，我选择了Application作为EditorApp.application。添加了EditorApp（我的应用程序）作为依赖项，并添加了所需的插件。同样在配置选项卡下，我添加了插件的建议启动级别。
该产品正在出口。但是当我尝试运行该产品时，它会出现以下错误：

请注意， 1.当我从Eclipse运行它时，此应用程序正常运行。 2.我的项目中有Application.java文件。但是，我把它保存在包中 - com.app.application。 Application.java的代码如下所示：
package com.app.application;
import org.eclipse.equinox.app.IApplication;
import org.eclipse.equinox.app.IApplicationContext;
import org.eclipse.swt.widgets.Display;
import org.eclipse.ui.IWorkbench;
import org.eclipse.ui.PlatformUI;
import com.app.editor.ApplicationWorkbenchAdvisor;
/**
* This class controls all aspects of the application's execution.
*/
public class Application implements IApplication {
/*
* (non-Javadoc)
*
* @see org.eclipse.equinox.app.IApplication#start(org.eclipse.equinox.app.
* IApplicationContext)
*/
public Object start(IApplicationContext context) throws Exception {
Display display = PlatformUI.createDisplay();
try {
int returnCode = PlatformUI.createAndRunWorkbench(display,
new ApplicationWorkbenchAdvisor());
if (returnCode == PlatformUI.RETURN_RESTART) {
return IApplication.EXIT_RESTART;
} else {
return IApplication.EXIT_OK;
}
} finally {
display.dispose();
}
}
请建议。
谢谢！

更新：更改了上面的代码，我现在已经从classpath中删除了jar文件。现在，应用程序正在运行，但是在访问jar（例如数据库连接）时它会中断。
答案 0 :(得分：2)
您的build.properties文件未在构建的插件中包含类文件。您必须在.列表中加入bin.includes：
output.. = bin/
bin.includes = plugin.xml,\
.,\
META-INF/,\
library/
如果您正在使用其他jar，则应将它们添加到插件中（使用RCP外部的Jars非常棘手）。
例如：
output.. = bin/
bin.includes = META-INF/,\
.,\
plugin.properties,\
plugin.xml,\
lib/jogg-0.0.7.jar,\
lib/jorbis-0.0.15.jar,\
lib/vorbisspi1.0.2.jar
这里我的插件的'lib'目录中有三个jar。
plugin.xml / MANIFEST.MF编辑器的“Build”选项卡允许您指定它。
您还必须在MANIFEST.MF的“Bundle-Classpath”标题中包含jar。所以对我的例子来说：
Bundle-ClassPath: .,
lib/jogg-0.0.7.jar,
lib/jorbis-0.0.15.jar,
lib/vorbisspi1.0.2.jar
注意：还必须指定.条目以包含主插件代码。
您可以使用plugin.xml / MANIFEST.MF编辑器的“运行时”选项卡的“类路径”部分指定它。
