Is there a way to stop NetBeans scanning projects?

Question

I don't have much memory on my PC and a pretty weak processor. Although netbeans is by far my favorite IDE it is almost unbearable to use on my present computer because of the project scanning that starts automatically when I open the program.

Is there a way to prevent netbeans from scanning projects?

Answer 1

In addition to creating smaller Projects for the folders you really work on and then a Project Group to group them (Mateng), you can try excluding folders that you will never work on such as images folders and so on. To ignore those folders, go to:

File > Project Properties > Ignored Folders > Add Folder...

From NetBeans Help:

The Ignored Files property is the opposite of the Include Path. These are files inside the PHP project that you want the IDE to ignore for FTP upload, scanning, etc.

My Netbeans 8.0.2 would crash on my Macbook pro due to "Scanning projects..." hogging up my CPU. I couldn't stop the process, however, I could make the process finish quicker by increasing the Java heap memory in netbeans.conf.

$ vi /Applications/NetBeans/NetBeans\ 8.0.2.app/Contents/Resources/NetBeans/etc/netbeans.conf

Replace this:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true"

with:

netbeans_default_options="-J-client -J-Xss2m -J-Xms2048m -J-Xmx2048m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true"

Answer 4

I don't know whether you can disable the project scanning or not. Even if you can, I doubt it will ever work properly again. There are a few tips which I have done and it speed up my Netbeans.

1. Close Tasks window. This prevents Netbeans to scan for TODO in the comments.
2. Exclude virus scanning for *.jar, java folders and netbeans folder. This speeds up my netbeans A LOT.

Netbeans consumes a lot of memory so adding memory also increases its performance (OS does not need to swap between memory and page file when memory is running low) (but this is probably not an option for you). Also, Netbeans consists of hundreds of files which needs to be loaded at start up so the bottom neck is the speed of your hard disk.

Answer 6

I have the quickest and easiest way.

Just put the netbeans metadata to another location instead of putting it on the project directory
