HA3: Maven dependency problems

Question

I am trying to set up the environment for the Home Assigntment. I'm using the SWSV image on the NIIF Cloud. I was following the steps written in the Project updates and environment issue but when I need to copy and rename the pom file I'm getting an error because the file and even the folder do not exist.

cp: cannot stat '4.1.3/core-4.1.3.pom': No such file or directory

My output for Java version:

java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (Zulu 8.42.0.23-CA-linux64) (build 1.8.0_232-b18)
OpenJDK 64-Bit Server VM (Zulu 8.42.0.23-CA-linux64) (build 25.232-b18, mixed mode)

What should I do?

Comments

I tried to delete the whole .m2 folder and restart the process but it did not help. When I first tried there was a core folder in ~/.m2/repository/eu/arrowhead but after serveral tryings it not created anymore.

Try to first compile from the src/arrowhead-java folder.

If you merged the updates successfully, there should be a pom.xml there, and the project should compile from there.

Was it successful?

Answer 1

Before any commands, first install the project into the local Maven repository with

mvn install -DskipTests

After that there will be a core folder with the main pom.
