查看eclipse的log。
如何查看呢？
eclipse -vm c:\jdks\java_1.4.2_06\jre\bin\java.exe -console -consoleLog
-debug -vmargs -Xmx384M
Gathering Information About Your Plug-in
http://www.eclipse.org/eclipse/platform-core/documents/3.1/debug.html
-debug options_file_full_path
if set to a non-null value, the platform is put in debug mode. If the value is
a string it is interpreted as the location of the .options file. This file
indicates what debug points
如果有debug，那么platform将进入debug模式。options_file_full_path是options文件的全路径。这个文件会给出哪些plugin的debug参数被设置成true，哪些debug参数
are available for a plug-in and whether or not they are enabled. If a location
is not specified, the platform searches for the .options file under the
install directory.
被设置成false。如果没有设置options_file_full_path，platform将在安装目录下面找.options文件。
-consolelog
if “true”, any log output is also sent to Java’s System.out (typically back to
the command shell if any). Handy when combined with -debug
如果设置了该参数，任何输出到log文件的log都会被输出到命令行。它和-debug参数一起使用很方便。
-console
if set to a non-null value, the OSGi console (if installed) is enabled. This
is handy for investigating the state of the system. If the value is a suitable
integer, it is interpreted
如果设置了该参数，OSGi的console会被打开(前提是OSG已经安装)。这个参数用来调查系统状态很好用。如果设置了端口好，
as the port on which the console listens and directs its output to the given
port. If the value is not a suitable integer (including the empty string) then
the console will listen
会监听这个端口，然后将输出重定向到给定的端口中去，如果没有指定端口
System.in and direct its output to System.out.
console将会在System.in上获得输入，然后在System.out上输出
将osgi中的所有debug参数设置成true的options文件：
