Error building mulesoft-ai-chain-connector

[JoseClua]

Hi,

I am trying to folow steps here:
https://mac-project.ai/docs/mulechain-ai/getting-started
to build the mulesoft-ai-chain-connector with Java 17 in a windows environment.

the export command dosnt work on windows so I used set instead.

When running this command >mvn clean install -Dmaven.test.skip=true -DskipTests -Dgpg.skip -Djdeps.multiRelease=17

I am getting this error:

C:\Users\jlclu\AGENTFORCE\mulesoft-ai-chain-connector>mvn clean install -Dmaven.test.skip=true -DskipTests -Dgpg.skip -Djdeps.multiRelease=17

@alick888 @tbolis-at-mulesoft can you please help Jose?

Hey good news @amirkhan-ak-sf

The connector worked perfectly when doing the Option 1: Maven Central Repository approach. Just adding the dependency in pom file.
I should have tried this option first, I don't know why I went for Option 2 - Local Maven Repository lol

Anyway, I will close this. Thanks
