Maven Depedency：脱机命令问题

Question

I am trying to use the following command:

RUN mvn clean dependency:go-offline

and I get the following error:

[ERROR] Failed to execute goal on project wc-dao: Could not resolve dependencies for project com.whitecoats:wc-dao:jar:1.0: Could not find artifact com.whitecoats:wc-commons:jar:1.0 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

My project folder:

1)wc-aws(JAR)
    -pom.xml
    -src
2)wc-admin(spring project WAR)
    -pom.xml
    -src
3)wc-dao(JAR)
    -pom.xml
    -src
-pom.xml

As I understand, maven is trying to look for an artifact online. But the artifact is local java project (wc-dao) which my wc-admin(main project) is dependent on.

How to resolve this?

The Error occurred in the following environment:
Docker:

FROM maven:3.6.1-jdk-8 as maven_builder

ENV HOME=/app

RUN mkdir $HOME

WORKDIR $HOME

ADD . $HOME

RUN mvn clean dependency:go-offline

RUN mvn clean install -T 2C -DskipTests=true

How to resolve the issue?

Answer 1

Maven misses the artifact

 com.whitecoats:wc-commons:jar:1.0

which seems to be not included in your project.

Answer 2

Could not find artifact com.whitecoats:wc-commons:jar:1.0

You need to install wc-commons into local maven repository to be able to access it from another project, use:

mvn install -pl wc-commons
mvn dependency:go-offline

Don't forget to use correct version of wc-commons dependency: it should be the same as in pom.xm file of wc-commons .
