Error while building the project #42

Closed dareenkf closed 3 years ago

dareenkf commented 3 years ago

Hi, I tried to run the project, but unfortunately I got this error. [ERROR] Failed to execute goal on project sdg-cli: Could not resolve dependencies for project es.upv.mist.slicing:sdg-cli:jar:1.2.4: Failed to collect dependencies at es.upv.mist.slicing:sdg-core:jar:1.2.4: Failed to read artifact descriptor for es.upv.mist.slicing:sdg-core:jar:1.2.4: Failure to find es.upv.mist.slicing:sdg:pom:1.2.4 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

I checked the ~/.m2/repository/es/upv/mist/slicing/sdg-core/1.2.4/ , and I found both (sdg-core-1.2.4.jar & sdg-core-1.2.4.pom ). Do you have an idea why I got this error?

Hi there! Weirdly, I get the same error on Linux, but it didn't appear on macOS under the same mvn version.

I think the correct solution is to call mvn package from the root of the repository, instead of individually compiling each module. This takes care of the dependencies automatically and you can find sdg-cli-{version}-with-dependencies.jar in sdg-cli/target/. The more specific command would be mvn package -pl sdg-cli -am, but mvn package works (though it packages both modules). I've tried it in Ubuntu (Maven 3.6.3), so it should work for you too.

I really don't understand how Maven can't find the dependency in the local repo, if you ever find out why, I'd be interested to know.
