1. "Help"-> "Software Update"-> "find and install"-> "search for new feature components to be installed"-> "create remote site" (this method is used for online updates)
2. "Help"-> "Software Update"-> "find and install"-> "search for new feature components to be installed"-> "Create local site" (if the plug-in has been downloaded to a local, please do not use the first method)
3. Directly copy the contents in the plugins and features directories and place them under $ eclipse_home $/Corresponding plugins and features.
4. Associate external links with external plug-ins
The first method is generally used, while the second or third method is usually used for most raw hands. The advantages and disadvantages of these four methods are as follows:
The first three methods will copy the plug-in files to the plugins and features directories corresponding to $ eclipse_home $/. Essentially, there is no big difference, and the plug-in can only be installed and disabled, you Cannot uninstall the plug-in. (If you are familiar with the directories and files corresponding to the plug-in, you can directly Delete the copied files to uninstall the plug-in ), however, method 1 and method 2 are prone to errors or conflicts when installing plug-ins, especially when you use the myeclipse plug-in and Chinese package, if you want to install plug-ins such as hibernatesynchronizer, Jode Compiler (class decompilation tool), and visual editor, the myeclipse plug-in and Chinese package may become invalid.
Therefore, if the plug-in has been downloaded to a local device, copy it directly to the $ eclipse_home $/plugins and features directory, that is, method 3 to avoid conflicts.
Method 4: store all the plug-ins in an external directory. If it is D:/plug-in, copy all the plug-in directory files shown above to this directory, for example, the file path of the Tomcat plug-in isD:/plug-in/tomcat_plug/Eclipse/plugins/COM. sysdeo. Eclipse. tomcat_3.1.0.beta(Note that method 4 must strictly place files in such directory paths ). Create a links directory under $ eclipse_home $ and create an associated file under the links directory. For example, tomcat. Link, add the following statement to the associated file:
Path =D: // plug-in // tomcat_plug
You can also write the following form
Path = D:/plug-in/tomcat_plug
It can also be written as a relative path.
For the rest, I don't need to say that you know everything. Restart eclipse, enter the eclipse installation directory in the DOS window, enter the eclipse-clean command, press enter, or enter$ Eclipse_home $/configuration directory. Delete org. Eclipse. Update and restart eclipse.
