2017.4.17 Custom Eclipse Content Assist (code completion), such as the spacebar "=" key not on the screen

Eclipse has the code hint feature, but the default hint is only the input "." , we want eclipse to be able to automatically prompt you to enter any letter, as in Visual Studio, and modify it as follows:

1. "Window" → "Preferences" 2. Select Java, expand, Editor, and select Content Assist. 3. Select "Content Assist" and see the "Auto Activation triggers for Java" option under "Auto-activation" on the right and right. Actually, it means "." is the trigger code hint. This symbol. 4. "Auto Activation triggers for Java" option in "." After adding abcdefghijklmnopqrstuvwxyz letters, easy to find the following changes. Then "Apply" and click "OK".

According to the above method to write code can be implemented at any time code hints and complete function, but in the use of the problem comes again, when the space bar will be the first line of content automatically screen, in fact, many times is to lose a space. How to solve, search on the internet a bit, sure enough someone encountered the same problem, refer to the following solution, successfully in Eclipse 3.7 to solve the problem.

How can I not find src This folder of UM may be related to the source , you find your Eclipse IDE for Java EE developers Plugins directory below there is no source code of org.eclipse.jface.text

Eclipse 's Plug-in development environment (PDE) plugin URL: http://www.eclipse.org/pde/

I have also installed Eclipse 3.5 and Eclipse 3.7, as instructed in the above article, the plugin source code cannot be modified under Eclipse 3.5 , and in Eclipse 3.7 Can be modified successfully .

The "Plug-in development" option is not available under the Eclipse 3.5 Galileo "Import" dialog box , and cannot be on the plugin under Eclipse 3.5 " Org.eclipse.jface.text " source code to modify .

The Eclipse 3.7 "Import" dialog box has the "plug-in development" option, which can be used for plugins under Eclipse 3.7 " Org.eclipse.jface.text " source code to modify .

"Import as" needs to select "Projects with Source folders"

Export the modified project, and then use the exported "Org.eclipse.jface.text_3.7.1.r371_v20110825-0800.jar" plug-in to overwrite the original corresponding plug-in is good .

has been modified "Org.eclipse.jface.text_3.7.1.r371_v20110825-0800.jar" I have uploaded to my resources, need to download.
