1. Download Ext 4.x, unzip it, do not delete the src folder..
2. Select the menu item Window > Preferences... to open the workbench preferences.
3. Select the Spket > JavaScript Profile preference page to display the installed JavaScript Profiles.
4. Click the New.. button. In the Name field, type Ext 4 as the name for the new profile. Then clickOK.
5. Click the Add Library button. From the Library drop-down list, select ExtJS. Then click OK.
6. Click the Add File button, choose sdk.jsb3 which can be found in build folder.

8. If everything done correctly, your profile should looks like this.
9. Click on OK to save the preferences.
10. Open javascript file with Spket JavaScript Editor. If you not sure which editor you used, take a look at this screen shot. click Ctrl+Space or Alt+/, the code assist window will looks like this if there is no code.

Caution

For Ext 4.1.x, before creating profile, you have to move sdk.jsb3 from extjs-4.1.x/build to extjs-4.1.x

但是ext4.2中并不好使 原因是没有了sdk.jsb3这个文件，所以要用导入文件夹的方法来安装
