Hi,

We are trying to load the new plugins like before from directories and not the ~/.m2.
And got the following error :

ERROR:GateAnnotate:initController():Unable to load gapp file:com.thoughtworks.xstream.converters.ConversionException: No converter available

Is there a way to convert the new Maven plugin format to be used like before from a directory.
This is because we don't want to use Maven and need to package the whole GATE rules, gazetteers and plugin to be used without access to internet.

Thanks for any pointer, we already searched the doc, forum, github, etc.
We also tried to use the zip from Export for GATE Cloud.

Hi Thomas,

I don't think there is any way to load the Maven based plugins from a directory like you could with the old directory based plugins. If you just want a self contained package though that contains an app and all it's dependencies then you just need to use the Export for GATE Cloud option. That produces a maven-cache.gate folder next to the xgapp file. That folder contains cached copies of all the maven dependencies needed for the app to load; which contains all the pluigns. That means you can then load the xgapp into GATE without needing any internet access etc.

You seem to suggest that option doesn't work for you. Can you explain why not, because if it doesn't fully work then that might in fact be a bug in the caching mechanism,

Thanks Mark and Ian for your answers.

We solved our problem with your hints.

We are using the last version 9.1 and copied jar from gate developer lib in our software lib directory.

Indeed you're right "Export for GATE Cloud" is the way to go.

We didn't use the maven and plexus jar because we didn't want to have dependencies on maven.
Unfortunately that gives us this error message.

Our customers use GATE on their confidential documents and hosted offline on premises so Maven needing network connection is less suitable for our setup.

Thanks again,

Thomas

If you are using an export for GATE Cloud then Maven does not need a network connection. If you are specifically worried about it then there are things you can do in settings.xml to change how Maven works. There are lots of options you can use and I don't have a good example to share. One option might be a to set a proxy that doesn't chain back to the main repo. And of course there are probably machine level configurations you could make to limit Maven's ability to connect to the internet as well
