eclipse 插件开发导出jar包到plugin 插件不显示_eclipse导出插件时显示没有插件-优快云博客

故事情节：

插件项目选择 run as eclipse application是正常的，也可以看到插件，也是可以用的，但是导出成jar包放到eclipse下面的plugin里面就是看不到插件
导出方法如下：

刚开始是以为导出的方式有问题，然后我又怀疑我的构建路径是否有问题，检查后发现一切正常，我又开始猜测是不是我创建eclipse plugin项目时候选择的eclipse版本和本eclipse版本不一致，调整后发现问题还是在，我又开始怀疑是不是我的jdk版本有问题，我又重新创建了一个eclipse plugin项目，应为我的eclipse用的jdk1.6,所以我选择了jre1.6，但是还是不行

经过这两个晚上的网上搜索得到了重要的解决这类问题的办法，在此我不得不承认http://stackoverflow.com/是个好网站，在里面我获得了重要的信息，我访问了eclipse官网的Where Is My Bundle栏目。

在里面列举出了eclipse插件的各种状态和osgi控制台的常用的命令

INSTALLED - This means that OSGi knows about your bundle but there is something wrong and it couldn't resolve. Problems may include thing from missing dependencies to requiring a higher Java VM version than you are running with. To get more information on why your bundle is not resolved try running the diag <bundle id> command, where <bundle id> is your bundle id or bundle symbolic name.
RESOLVED - If your bundle is resolved but you expected it to be started, then try starting your bundle from the command-line with the start 123 command. If it won't start, then you should get some feedback as to what the problem is.
<<lazy>> - This means your bundle is resolved and is marked to be lazy started. Everything should be ok.
ACTIVE - your bundle is resolved and has been started, everything should be working as planned.

果断在osgi的控制台下输入命令ss

结果：

1056	<<LAZY>>    com.taobao.eclipse.plugin.autodao.ibatis_1.3.0.201206051529
1057	<<LAZY>>    com.taobao.eclipse.plugin.autodao.ui_1.3.0.201206051529
1058	<<LAZY>>    se.oixx.fastfox_1.5.0

1066	<<LAZY>>    net.java.amateras.umleditor.java_1.3.4
1067	RESOLVED    net.java.amateras.xstream_1.3.4
1072	INSTALLED   TestCase_1.0.0
1075	INSTALLED   Fish4j_1.0.0

敲入命令 bundle 1075

osgi> bundle 1075
Fish4j_1.0.0 [1075]
  Id=1075, Status=INSTALLED   Data Root=E:\products\CS\eclipse-jee-helios-win32-x86_64\eclipse\configuration\org.eclipse.osgi\bundles\1075\data
  No registered services.
  No services in use.
  No exported packages
  No imported packages
  No fragment bundles
  No named class spaces
  No required bundles

敲入命令 diag 1075

osgi> diag 1075
reference:file:plugins/Fish4j_1.0.0.jar [1075]
  Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.7

这样才有了解决方案，不会像之前那样去毫无目标和证据的猜测，果断把eclipse运行环境调成jdk1.7问题就搞定了，可以睡觉了
