M3)¶

Currently the Eclipse with bundled JRE does not yet support M1. We recommend downloading Spoofax Eclipse without the embedded JRE. Then either use the JDK 8 that is installed by default on macOS M1/M2, or install your own.

To configure Eclipse to use an installed JDK:

In the Finder, right-click the Spoofax app, choose Show Package Contents.
Browse to Contents/Eclipse.
Edit the eclipse.ini file.
Replace or add two lines at the top of the file with the -vm argument:
```
-vm
<path>
```
Where <path> is the path of your JDK, using one of the approaches below.

Using macOS default JDK¶

If you want to use the default JDK 8 that is installed with macOS, you can verify its version number:

java -version

This should print something like:

java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)

The -vm path you should use in this case should be something like:

-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home/bin

Installing a custom JDK¶

To install and use a custom JDK for Spoofax, we recommend using a MacOS pkg installer. Note that only an x86 JDK is supported. We tested this with JDK 11 (recommended) but Java 8 and newer should work.

Once installed, the -vm path in the Eclipse installation should be something like:

-vm
/Library/Java/JavaVirtualMachines/temurin-11.jdk/Contents/Home/bin/java
