How do you install MIT AI2 offline in Linux based OS?

[Shanmuga_Nathan]

Linux & Mac
chmod +x startAIServer.sh (ONLY THE FIRST TIME)
./startAIServer.sh (and go to url: localhost:8888)

tried above, but not launching
output is

[TIMAI2]

Are you already using port 8888 for another service? If so you need to change either that or the port AI2 will run on. However, it could be that you already have the Ai2 service up and running, and need to shut that down before starting a new session.

[Shanmuga_Nathan]

ok will restart my PC and try again

[Shanmuga_Nathan]

Hurrah!
It works Fine (both Companion and ai2)
But Build server gets this issue

[Shanmuga_Nathan]

nothing solved the issue

[Peter]

As you can see it would be a guessing game if you dont tell anything about your project.

[Shanmuga_Nathan]

@Peter

about your project.

Just inserted check box and button, in order to test the software

[TIMAI2]

Does the project compile in proper AI2?

[Shanmuga_Nathan]

Yes, I just also tried in normal ai2

[Peter]

I got the same here. hmmmm some testing to do

[Shanmuga_Nathan]

I hope you come up soon with a solution, and I'm waiting for it

[Peter]

Strange it has worked before. Something has changed but I don't know what.

[Shanmuga_Nathan]

Ohh! Ok let's check in next updated version

[Ramiro]

Parece que esta utilizando la version de java que viene por defecto en linux que es java 11, para que funcione correctamente se debe usar java 8 en su lugar.

java -version

sudo apt-get update

sudo apt-get install openjdk-8-jdk

java -version

sudo update-alternatives --config java

sudo update-alternatives --config javac

[Peter]

Brainfart. I got this problem in the past but didn´t think about it. I got myself a new laptop some weeks ago and on my old one it was working. Thanks for keeping me away from spending to much time in finding the problem. I hope i will keep it in mind the next time.

[Anke]

I think we have already discussed this problem (JDK 8 for AI2Offline) extensively, for example here:
