如何在 NetBeans 8.2 中设置默认 Java 平台？

Question

I want to set the default Java Platform which is used to build my projects in NetBeans 8.2 (netbeans_jdkhome).

Prior versions allowed me to do that. See this answer .

The only problem is that I want to set this platform to be 1.7 (instead of current 1.8), but NetBeans 8.2 requires to run on 1.8, so I cannot have 1.7 as the default Java Platform.

Is there a way to override it?

Answer 1

You can get your default JDK by: Tools - Java Plattforms . There you can add all your JDKs and watch their bibs. If you want to change the default one you need to go the path: C:\\Program Files\\NetBeans 8.2\\etc and you need to change the netbeans.conf

In line 57 (in mine) you see something like this:

netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_66"

Change the Path to your wanted JDK and you´re finish.

Here a longer description.

Answer 2

For now, it appears there is no way to override it, here is NetBeans Help about Java Platform Manager:

Use to register different versions of the Java Development Kit (JDK) and other Java tools that your programs depend on. The dialog box lists all of your registered JDKs in the left pane and lists the JDK that the IDE is running on as the Default Platform.

So I'll have to change platform for each project because Netbeans 8.2 can not run with JDK 1.7 (so I can't set it as default platform).

LenglBoy didn't even read my question, the same thing was done in the link I posted.

There is a recent plugin that allows to right-click maven projects to set the JDK (still cannot set it by default).

Answer 3

There is no eclipse like default option. You can set java platform for every imported project. Change JRE in NetBeans project

Here is how to set and change default JDK in NetBeans for Mac OS X users (tested with NetBeans IDE 12.5, should work with several other versions):

• Close NetBeans
• Navigate to the file "netbeans.conf" (path is usually /Applications/NetBeans/Apache NetBeans 12.5.app/Contents/Resources/NetBeans/netbeans/etc/netbeans.conf )
• Open the file with TextEdit or another editor of your choice
• In the document, search for the following line: #netbeans_jdkhome="path/to/jdk"
• Uncomment the piece of code by deleting the hash sign: netbeans_jdkhome="path/to/jdk"
• Change "path/to/jdk" with the path to the JDK you want to set as default JDK in NetBeans. Example: /Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home
• Finally the crucial line of code should look like this: netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home"
• Save the file you've just edited. The file was called netbeans.conf and it has to be the SAME name, saved in the SAME folder as before
• Open NetBeans
• Check if it worked: Go to Tools -> Java Platforms. On the left side you will see which JDK is set to default.

Hope this helped the mac users.
