Hey,

i had the same problem. just delete the org.antlr.runtime in your workspace and reload it while generating the xtext artifacts.

kind regards.

Hi Christian,

I use antlr 3.2.0 as prefered by itemis. Can you recommend a newer version?

for me it looks like during the update process,
in the existing projects something is setting back the "would you like to download ANTLR .." decision.

IMHO, we would need some way to reset this decision
so the next time we run the MWE2 for the *.XTEXT,
we will be prompted again to download ANTLR

Because I had only 5 simple experiments on XTEXT,
I solved it with a new workspace, new projects, ...

Hi

The downloaded file can be found in the project (if you did. Download it Once)

Hi Christian,

but after I applied the update, I got for my existing projects (which had a downloaded ANTLR3)
the above error and the recommendation
[INFO] Please use the ANTLR parser generator in version 2.1 or better

so something in the update process messed up my once-it-worked projects

Hi,

as i said: i think the expectation is to delete the downloaded file and redownload it. it searches for a file with name .antlr-generator-3.2.0.jar in the project.
alternatively you can install the antlr from http://download.itemis.de/updates/ and add it to your target platform.

Hi Christian,

this is the solution I was looking for.

The jar is located directly in the project directory.
I was prompted for the download after re-running the MWE2.

Thanks for your help
