Problem with NetBeans, it does not let me create or open projects


I have even been using NetBeans (version 8.2) to program in Java because I like this IDE but I do not know why it does not work correctly anymore, I click to create a new file or project and nothing opens and when I try to open a project I lets select it but as soon as I give it to open it does absolutely nothing, I have tried to delete all the folders related to the program and then reinstall it but it has not worked, until yesterday it worked perfectly, any idea of what happens and What can I do?

Apparently the program started to use jdk9 which is the cause of the problem but I told him to use jdk1.8.0_151 and it is all solved.

Before installing an IDE you should review your requirements , I use Netbeans 8.1 which requires Java SE Development Kit (JDK) 7 Update 10 and for version 8.2, the requirements are:

  • Java SE Development Kit (JDK) 8 is required to install NetBeans IDE. You can download the latest update of JDK 8 in    link .
  • The NetBeans packages of PHP and C / C ++ only require the Java Runtime Environment (JRE) 8 to be installed and executed. JDK 8 is required if   plan to use any of the Java features
  • JDK 8 is required to use JavaFX 8 features in NetBeans IDE 8.2.

The same thing happened to me. When reading AlejandroLL's message I looked at my installed programs and had two different versions of JDK installed, I eliminated the versions of JDK 9 (Java 9 and Java SE Development kit 9). When reopen Netbeans asked me if I use the default configuration, there you say 'Yes' and everything goes great.

Apparently there was some conflict with versions 8 and 9 of JDK.

You only need to rename a folder that is called 8.2 by _8.2 to solve the problem in netbeans 8.2 that does not load the history or rather the main, when creating a new application this is the solution.

Go to the local disk (c:) \ Users \ user_name \ AppData \ Roaming \ NetBeans.

in the Netbeans folder you will find a folder with this name 8.2 rename it with _8.2 and that's it. do not forget to close before netbeans because it will not let you rename the folder.

First step: close netbeans. Second Step: go to the netbeans folder (above, I'll give you the route to get there) Third Step: rename the 8.2 caperta for _8.2 Step Four: open netbeans and create a new api. Step Five: You're happy because it's already working.
