Missing:
----------
1) com.erp:erp:jar:1.0-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.erp -DartifactId=erp -Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=com.erp -DartifactId=erp -Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency: 
    1) com.erp:erp-web:war:1.0-SNAPSHOT
    2) com.erp:erp:jar:1.0-SNAPSHOT

回答1:

Your artifact com.erp:erp:jar:1.0-SNAPSHOT is not found on all registered repositories. Thus, register an additional repository - if there is already any - that is serving your JARs.

If there is no repository yet serving your libs, then use one of the following solutions:

Install your libs in a local repository as stated in the Maven comment above: mvn install:install-file .... Please find more information about install:install-file here.
Use (or first install) a company wide remote repository such as Nexus and put your JARs to it as also stated in the Maven comment above using following command: mvn deploy:deploy-file .... Please find more information about deploy:deploy-file here.

Find some more information about repositories on the Maven website.
