Build and run from source

1. Install the required JDK
2. Install Apache Ant
3. Clone the repository

1
2

git clone https://github.com/apache/netbeans.git
cd netbeans

4. Run the build

1

ant

This command compiles the IDE and assembles the NetBeans platform.

5. Run NetBeans

After the build completes, you can start the IDE using:

1

./nbbuild/netbeans/bin/netbeans

Tips:

• Make sure JAVA_HOME points to the correct JDK
• Running ant clean helps if the build fails due to cached artifacts
• The nbbuild directory contains most of the build scripts and configuration

How can I set the JDK NetBeans runs on?

Update the netbeans.conf. You may need administrator privileges to edit the file.

/Applications/Apache NetBeans.app/Contents/Resources/netbeans/etc/netbeans.conf

and change the following line to point it where your Java installation is:

netbeans_jdkhome="/usr/local/opt/openjdk/libexec/openjdk.jdk/Contents/Home"
