Trouble installing MyRobotLab

[Franz A]

Hoi,
i have no success with installing MRL.

I did everything as supposed, i have the C:\MRL with the .bat,.sh,.jar as shown.

But when i click on the myrobotlab.bat nothing happens.
Shown in a DOS-Prompt there are several issues listed....i.e. no libraries\ directory.

I am running Win11..

Thanks so far for reading

Hello,

what java version did you install?

Hmmm,
where are my other postings and the answers from Users ????

I have several JDK installed (in cae of JAVE and ANDROID coding) but installaed also the ...18.

One mentioned to make an own myrobotlab.bat, but i couldn't find the posting anymore...

Regards
Franz

It could be that Myrobotlab selects java version 1.4, which wouldn't work.

If you have multiple java versions installed, you would need to define which version to run for Myrobotlab.

You need to create .bat file which points to your java23 and to the directory containing myrobotlab.bat

Here is an example:

echo setting java 11 environment

set PATH=%PATH%;C:\java\jdk-23.0.9\bin

REM this start an cmd shell with the appropriate env

cmd /k

REM you can get more elaborate if you want

REM cd to where Nixie is 

REM java -jar myrobotlab.bat

[Franz A]

I did as you mentioned.
With that batchfile i get this screen content:
---

C:\mrl\myrobotlab>myrobotlab.bat

C:\mrl\myrobotlab>echo setting java 11 environment
setting java 11 environment

C:\mrl\myrobotlab>set PATH=C:\Program Files\Common Files\Oracle\Java\javapath;C:\Java\jdk-18\bin;C:\mrl\myrobotlab;C:\Users\franz\AppData\Local\Microsoft\WindowsApps;;C:\java\jdk-24\bin;C:\java\jdk-24\bin;C:\java\jdk-24\bin;C:\java\jdk-24\bin

C:\mrl\myrobotlab>REM this start an cmd shell with the appropriate env

C:\mrl\myrobotlab>cmd /k
C:\mrl\myrobotlab>

[Franz A]

If i replace

java -jar myrobotlab.bat

with

java -jar myrobotlab.jar

then something is happening, a huge amount of lines scrolling ...after a while it stopps with this line:
09:42:03.374 [main] INFO c.m.f.Service [Service.java:2262] runtime info setting virtual to false

after hitting enter it does some more and then stands at the prompt
[runtime@sudden-darth /]#

[gael langevin]

Good, it's progressing.

For info, because the prompt doesn't show any activity, the installation seems to stale , but it actually keeps installing dependencies.

I suggest you retry again the installation and let it be until it finalizes the process.

Make sure Chrome is set as default browser.

[Franz A]

Chrome is standardbrowser.

This is the screen after starting....and nothing will happen (over hours):

This is the last part i saw, before there is a ASCII screen etc. and many screensides rolling up...

Behind the # in the last row the cursor is blinking (as in good old CPM and DOS times... ;-)

I just tried a fresh install and all went as expected.

I suspect your previous attempts to install without defining the proper java version might have corrupted some files.

Delete the .ivy2 directory , (its the myrobotlab cache) It will be recreated  when you make a fresh install.

The  myrobotlab cache is located in C:/Users/yourname/.ivy2

Also delete everything (except myrobotlab.bat and myrobotlab.jar) in your directory myrobotlab-1.1.1605.

And finally run your special bat file to define the java version.

[gael langevin]

The  myrobotlab cache is located in C:/Users/yourname/.ivy2

If there is no .ivy2 that means the install did not proceed at all.

[Franz A]

I tried all the described help on 2 computers.
None of them has a directory named .ivy2 (and i marked in the explorer to show also hidden elements).

I cant believe that it is so hard to install this MRL...must there some ports be free in the firewall or what could that problems cause ?

Merci beaucoup so far for your help.
8 years ago i installed it without problems....

[gael langevin]

It's hard to evaluate what is wrong with your PC. 

MRL is installed on many devices every week without issues, it is normally pretty straight forward.

Are your java versions allowed to access private and public networks?

[gael langevin]

Maybe your bat file for selecting the java version is not proper. Here is how mine is looking:

[Franz A]

Yes, all networks.

I did as you say, delete all of the content instead the named ones.
After starting again at once there a 3 directrories build up in c:\mrl\myrobotlab:
- data

- libraries

- ressource

For now it stands again at the point

i see your are using a .bat for starting the myrobotlab.bat: what is the content of that file ?

[Franz A]

Oops...frustrated i set the java to 14.0.1 - TADAAA ! (so far ;-) )

[Franz A]

Also on my Developer NB it is inst

alling now :-)
This file works....some " to much there...

[Franz A]

On both computers Myrobolab is now running....many many thanks to Geal and the others that helped me.
Its like always: never give up !

Now i have issues uploading MRLCOMM.ino to the Mega2560...but that's another story....

[gael langevin]

Finally it is installed!

In most cases if you cannot upload the MRLComm.ino, you need to downgrade of Arduino.exe.

I use version Arduino 1.8.15 and it uploads just fine.
