Coffee Editor Installation Issue after adding "mvn" to yarn

[RagipSelcuk]

Hi all,

I'm a newbee on this platform and I intended to use eclipse thei to create a custom IDE for automotive applications based on AUTOSAR.

In case of investigating the Coffee Editor, I have encountered the following failure, please give me suggestions to resolve this issue.

I follow the Readme.md section. After adding the "mvn" , I get below message;

PS D:\7- AutosarSandbox\GitHubTheia\coffee-editor> yarn build
yarn run v1.23.0-20200615.1913
$ yarn build:backend && yarn build:client && yarn copy:servers
$ cd backend/releng/org.eclipse.emfcloud.coffee.parent && mvn clean verify

Hi @RagipSelcuk,

Maven has be installed separately (and is usually not installed via yarn) - please see https://maven.apache.org/install.html
HTH and if there are any more issues please let me know.

BR, Nina
