If you set up Olingo, they have you run a Maven archetype (project template) like so:
mvn archetype:generate \ -DinteractiveMode=false \ -Dversion=1.0.0-SNAPSHOT \ -DgroupId=com.sample \ -DartifactId=my-car-service \ -DarchetypeGroupId=org.apache.olingo \ -DarchetypeArtifactId=olingo-odata2-sample-cars-service-archetype \ -DarchetypeVersion=RELEASE \
If you didn’t follow the instructions correctly, you’ll get the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.2:generate (default-cli) on project OlingoSampleClient: A Maven 2 project already exists in the directory d:\projects\odata\my-car-service -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException
All what this means is that you need to make a ‘project’ folder, move everything into it – Maven doesn’t like the .pom file in the current folder:
gary@GARY-PC /d/projects/odata $ ls my-car-service pom.xml project
