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.
However when I launch the STS application itself I have a pop up saying "Missing tools.jar"
I have already tried:
JAVA_HOME to different JDK -vm args in the .ini file.Yet I cannot get rid of this pop up.
The fix is in the -vm parameter. the order and the absolute path of the javaw.exe seems to be the issue.
the readme file mentions _ "To run Eclipse with an alternate Java runtime environment, the path to the Java virtual machine's binary must be identified. With an Eclipse installation from the distribution, altering the $PATH variable to include the path to the alternate Java runtime environment is often not enough as the Eclipse that Linux distributions package often performs a scan internally to pick up GCJ by itself whilst ignoring what's on the $PATH."
So I have edited now the SpringToolSuite4.ini and made this entry
-vm
C:\UserTemp\Softwares\java\jdk\oracle-jdk-1.8-64bit\bin\javaw.exe
Restarted my STS and it works perfect.
The reference to set the JVM Specifying the JVM was very useful in understanding this.
I solved this same problem by modifying the file "eclipse.ini". First I tried to solve it by modifying the file SpringToolSuite4.ini, but nothing happened, because I previusly had installed the eclipse ide, and the change in SpringToolSuite4.ini didn't work. then I modified the file eclipse.ini; and it worked.
The changes that I did in eclipse.ini are detailed below:
To check with what Java version (JRE or JDK) Eclipse is running, do the following:
Depending on the name and location of the used Java binary one can figure out if a JRE or a JDK is used:
If no JDK is used for Eclipse, change it:
Before the line -vmargs, add two lines:
On the first line, write -vm
On the second line, write the path to your JDK installation (usually something like: C:\Program Files\Java\jdk1.6.0_31\bin\javaw.exe on Windows)*
springtoolsuite4.init is not work for me, because i have no springtoolsuite4.init. –
Byrn eclipse.ini. It's worth to note that it should be two lines. –
Malefactor The fix is in the -vm parameter. the order and the absolute path of the javaw.exe seems to be the issue.

Don't spend too much time looking for tools.jar. If you get an error like that, don't be upset.
If you already have java JDK1.8, go to its lib folder, tools.jar should be available there. Copy and paste the same in JRE1.8 lib folder.
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
-vm pointer position didn't work, rather it needs to be in the beginning of the file, it seems, as per Martin's suggestion: #60081514 –
Jaguarundi SOLUTION :
Check your Path JAVA_HOME - system property "Environment Variables"
for example: JAVA_HOME:
C:\Program Files\Java\jdk-12.0.1\lib
usually you only need add \lib at JAVA_HOME
Just remove this line from variable "Path"
"C:\Program Files (x86)\Common Files\Oracle\Java\javapath"
System Properties > Advanced > Environment Variables > Path > Edit > Reboot
Worked for me
In my case I had installed jre, and not jdk!
Observe that you have jdk installed!
I had the same issue when i upgraded to Java 11.
I simply edited SpringToolSuite4.ini and added
-vm C:\Program Files\Java\jdk-11.0.4\bin\javaw.exe
For me, I had to do two things to make it work:
By downloading the tool file and paste it in the jre\lib path. but make sure you should rename the pasted file as "tools.jar".
step 1 download the tool file. download link http://www.java2s.com/Code/Jar/t/Downloadtools160jar.htm
step 2 extract the zip file.
step 3 you should rename the included .jar file as "tools".
step 4 then copy the renamed tools.jar file and paste in the C:\Program Files\Java\jre8\lib\ path.
then restart the STS ide.
Copy JDK directory to your STS installation or extraction library and and rename JDK to jre. the directory structure of STS should look like this
.eclipseproduct
artifacts.xml
configuration
dropins
eclipsec.exe
features
jre
license.txt
META-INF
open-source-licenses.txt
p2
plugins
readme
SpringToolSuite4.exe
SpringToolSuite4.ini
Once STS open, initially its looking for tools.jar in jre\lib folder its not available in jre\lib folder.
so we need copy the tools.jar from jdk\lib folder and paste in jre\lib folder.
restart the STS, issue will resolve.
