Missing tools.jar when launching STS application

Question

I have the latest STS4. I am using installed java-1.8 JDK not embedded as the execution environment. My project just runs fine without any issue.

Answer 1

I have STS4 so I have modified SpringToolSuite4.ini

I changed from:

[...]
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.8
[...]

to exactly this

[...]
--launcher.defaultAction
openFile
-vm
C:\Program Files\Java\jdk1.8.0_152\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.8
[...]

And the message dissapeared
