How to fix MojoFailureException configuring Olingo

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
Exit mobile version
