How to Specify Java Version in Tizen Studio on macOS

Original Created Jan 03, 2020 | Regeneration Apr 22, 2026

Question

I'm unable to run Tizen Studio because it's using OpenJDK runtime instead of my preferred Oracle Java 8 installation. The issues I'm facing are:

Tizen Studio doesn't respect my JAVA_HOME environment variable settings
Modifying eclipse.ini doesn't change the Java version being used

I need to configure Tizen Studio to use Oracle Java 8 without uninstalling my existing OpenJDK installations. I'm currently running macOS.

Answer

Problem Understanding

Tizen Studio, which is based on Eclipse, doesn't automatically use the Java version specified in JAVA_HOME during startup. This is a common Eclipse behavior where the environment variable isn't read at boot time.

Solution Methods

Modify eclipse.ini:
- Locate the eclipse.ini file in your Tizen Studio installation directory
- Add the following lines at the beginning of the file (before any -vmargs):
```
-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin
```
- Replace the path with your actual JDK 8 installation path
- Save the file and restart Tizen Studio

Alternative Method:

Create a symbolic link to force Tizen Studio to use your preferred JDK:

sudo ln -sfn /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home /Library/Java/Home

Code Examples

For the eclipse.ini modification:

-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin

Additional Tips

Make sure to add the -vm argument before any -vmargs in eclipse.ini
Verify your Java installation path using:
```
/usr/libexec/java_home -V
```
After making changes, restart Tizen Studio completely for the changes to take effect
