Setting, tuning and using eclipse (solving problems such as startup jam)

Eclipse tuning generally does not set up eclipse. When using eclipse, you will always feel that it is slow to start and easy to use. In fact, as long as you configure the relevant parameters of eclipse, it will be greatly improved. Speed up startup 1 When eclipse starts, it always searches for the JRE that makes it run. It is often this search process that slows down the start of eclipse. (if it is not set, the progress bar will appear in 2-3s, and the progress bar will appear directly after setting) just add the - VM parameter to eclipse.ini. 2. Cancel all plug-ins to be activated at startup (the same is true for activation during use) and other related operations performed during startup. 3. Turn off automatic update to reduce the problem of eclipse card caused by JVM memory recycling. This is mainly because when the JVM is in client mode, it will stop all other work and perform other tasks after recycling. During this period, eclipse gets stuck. Therefore, add JVM application appropriately Please the memory size to reduce the number of recycling, or even not recycling, the card phenomenon will be significantly improved. The of heap memory is mainly set through the following JVM parameters:

My configuration (2G memory notebook): there are other relevant parameters. You can see the following reference materials. It is very enlightening: - XX: + useparallelgc uses concurrent memory recycling - XX: + disableexplicitgc to disable the display of memory recycling eclipse related settings of system. Gc() to reduce the phenomenon of card 1 Turn off auto build. When it is too laggy, eclipse will automatically build the whole project for us, so that for large projects, every time it saves, it will cause a lot of cards. In fact, automatic build is not necessary at all. Just make sure to build it once before running, and eclipse will build it for us automatically before running, so closing is the wisest choice. 2. Turn off spell check settings 3 Close saveaction. The operation that will be performed during each save will seriously slow down the save, especially when the file is large. In fact, as long as you develop good programming habits, you don't need this at all. 4. Optimize code prompt. 5. Solution to the problem that eclipse is stuck by pressing the CTRL key when editing about 30000 lines of code in eclipse, eclipse often gets stuck for a long time when copying with Ctrl + C / v. Later, I found that as long as you press the CTRL key, you will get stuck. I guess it is because you can click and jump to the place where the variable is defined after pressing the CTRL key in eclipse. Therefore, when you press the CTRL key, eclipse will generate this mapping. When the file is large, this behavior will take more time. It is very uncomfortable. It is known after some searching, You can set shortcut keys in the following ways. Eclipse -- windows - > Preferences - > General - > editors - > text editors - > hyperlinking: remove this option: enable on demand hyperlinks style navigation or uncheck the files you don't want to Ctrl jump!

There are detailed instructions on how to use it in its help file. Generally, you can go there to find it. Code collapse setting shortcut key setting compiler error Warning setting local history setting code formatting setting library setting text editor setting allows eclipse to launch multiple instances workspace setting XML editor setting appearance setting code formatting style setting prompt when mouse over code etc. setting template setting when creating a new file JUnit launcher setting. When developing Android, if you can't use the built-in launcher in eclipse, you must use the launcher provided by Android. Eclipse uses the file comparison eclipse column editing mode search function (another is find / replace) to open a file multiple times, so you don't need to roll up and down when you need to refer to different parts of the file when writing code.
