改造easyexplore插件

1.如果选中的是目录，则在资源管理器中打开这个目录（而不是在它的上级选中该目录）；2.如果选中的是文件，则资源管理器中打开所在的文件夹并选中这个文件；另外，顺便把新的xp风格图标给拿了过来。

easyexplore的cvs地址是[e-mail]:/cvsroot/easystruts，下载源码之后发现easyexplore已经悄悄的更新了，多了“执行外部命令”等功能，图标也改成xp风格，不过多了一层子菜单，感觉不如原来方便，而且我只对explore这个功能感兴趣，所以只取回org/sf/easyexplore/EasyExplorePlugin.java，org/sf/easyexplore/actions/EasyExploreAction.java和org/sf/easyexplore/preferences/EasyExplorePreferencePage.java三个文件的1.1版本进行修改。代码是相当的简单：

在EasyExplorePlugin.java中改变defaultTagert的值：

protected void initializeDefaultPreferences(IPreferenceStore store) {
        String defaultTarget = "shell_open_command {0}";
        String osName = System.getProperty("os.name");
        if ( osName.indexOf("Windows") != -1 ) {
            defaultTarget = "explorer.exe /e,";
        }
        else if ( osName.indexOf("Mac") != -1 ) {
            defaultTarget = "open";            
        }
        
        store.setDefault(EasyExplorePreferencePage.P_TARGET, defaultTarget);
    }

在EasyExploreAction.java中增加一个判断条件，如果选中的文件那么在资源管理器中也选中之:

public void run(IAction action) {
        try {
            if ( "unknown".equals(selected) ) {
                MessageDialog.openInformation(new Shell(),"Easy Explore","Unable to explore " + selectedClass.getName());
                EasyExplorePlugin.log("Unable to explore " + selectedClass);
                return;
            }
            File directory = null;
            if ( selected instanceof IResource ) {
                directory= new File(((IResource)selected).getLocation().toOSString());
            } else if ( selected instanceof File ) {
                directory= (File) selected;
            } 

            String target = EasyExplorePlugin.getDefault().getTarget();
            
            if (!EasyExplorePlugin.getDefault().isSupported()) {
                MessageDialog.openInformation(new Shell(),"Easy Explore",
                    "This platform (" + 
                    System.getProperty("os.name") + 
                    ") is currently unsupported.\n" + 
                    "You can try to provide the correct command to execute in the Preference dialog.\n" +
                    "If you succeed, please be kind to post your discovery on EasyExplore website http://sourceforge.net/projects/easystruts,\n" +
                    "or by email [e-mail]. Thanks !");
                return;
            }

            if(directory.isFile() 
                && System.getProperty("os.name").indexOf("Windows") != -1 ) {
                target = target.trim() + "/select,";
            }
            if ( target.indexOf("{0}") == -1 ) {
                target = target.trim() + " {0}";
            }    
            
            target = MessageFormat.format(target, new String[]{directory.toString()});
            
            try { 
                EasyExplorePlugin.log("running: "+target);
                Runtime.getRuntime().exec(target);
            } catch ( Throwable t ) {
                MessageDialog.openInformation(new Shell(),"Easy Explore","Unable to execute " +target);
                EasyExplorePlugin.log(t);
            }
        } catch (Throwable e) {
            EasyExplorePlugin.log(e);
        }
    }
