How to fix classpath.txt in the startup directory no longer supported warning?

I've created Spring Boot Java project and i use Matlab (9.4.0.949201 (R2018a) Update 6, Java 1.8.0_144-b01). After find true version for the project (before this i've got "version of MATLAB Java Package that is not compatible with the version of MCR" error, to solve this problem i've changed my version of Matlab. 2023a -> 2018a). After changing version of Matlab, some errors were fixed. However, i got this error right now.

Warning: classpath.txt in the startup directory no longer supported. See <a href="matlab: helpview([docroot '/techdoc/matlab_external/matlab_external.map'],'java_static_path')">The Static Path</a>.

You can refer to the webpage below for reasons and a workaround for the warning message.

"To resolve this issue, launch MATLAB from a directory that does not include these files."

I tried some method but couldn't do that. How can i do this?

Would you try to follow the guidance below to restore your MATLAB settings to default?

-----------------------------------------------------

It seems that the problem you are experiencing is an abnormal operation of the product. Please apply the following instructions to initialize path and preference settings for the normal operation of MATLAB. If the following methods do not solve the problem, the only solution to the abnormal operation of the product is re-installation.

​Right-click on the MATLAB execution icon to run MATLAB in administrator mode, and then execute the following commands in the MATLAB command window.

​

>> restoredefaultpath

>> rehash toolboxreset

>> rehash toolboxcache

>> sl_refresh_customizations % Please run this line only when you use Simulink related products.

>> savepath

>> prefdir

​

If there is no problem executing each command (a warning message is ok),

Open the directory along the path that appears when the last command is executed. Then close MATLAB.

Go up to the parent folder of the open directory, rename R20XXx to R20XXx_old (Ex. R2020a -> R2020a_old). Then launch MATLAB.

I did what you advised me (i didn't use this sl_refresh_customizations) but I still have the same problem when i run -mvn clean install.
