To open “STS” you need to install the legacy Java SE 6 runtime

Question

I've just downloaded the latest version of Spring Tool Suite ( v3.9.5 ) for MacOS (High Sierra v.10.13.2) and when running STS I'm getting this error: To open “STS” you need to install the legacy Java SE 6 runtime.

When I checked what version of Java is installed with on my mac I get:

$ java --version
No Java runtime present, requesting install.

Similar issues with Eclipse and older MacOS versions:

Answer 1

Don't download old legacy Java

Go to Oracle and install the latest JDK .

Verify in Termial:

$ java -version
java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

STS will start now.
