考虑使用Eclipse日志记录。它在Eclipse Wiki中描述:http://wiki.eclipse.org/E4/EAS/Logging_and_Tracing
通过这种方式,您可以从RCP平台和您自己的日志记录共享相同的日志文件。这样可以更容易地关联日志文件中的事件。
如果您正在使用E4,则很容易注入日志服务(即您的插件不需要激活器类)。上面的wiki参考也描述了如何做到这一点。

log4j jar文件已打包为OSGi包。简单地放入目标平台的plugins文件夹(如果你将它作为目标,则放入Eclipse插件文件夹中),然后将其作为依赖项添加到项目plugin.xml中。

我建议您使用org.osgi.service.log.LogService
记录所有邮件,并添加LogListener
以将日志转发到您拥有的任何其他自定义日志(log4j,slf4j ......等)。通过这种方式,您不会丢失RCP框架所做的任何日志。

private Log logger = LogFactory.getLog(getClass());
您可以使用以下log4j.properties
条目更改日志文件位置log4j.appender.file.File = $ {workspace_loc} /。元数据/ MyLogFile.log

.article
在build.properties中添加引用。
bin.includes = plugin.xml,\
META-INF /,\
,\
LIB / log4j的-1.2.17.jar
在.java文件中使用记录器。
PropertyConfigurator.configure(log4jConfPath);
LOGGER.debug(“启动应用程序......”);
我发现本教程很有帮助。请检查 - Add log4j in RCP
