Failed to import project Maven dependency

[Languomao]

When I introduced Maven dependencies for a project, the following error occurred:

[INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 08:56 min [INFO] Finished at: 2020-03-04T01:34:24Z [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal on project submarine-client: Could not resolve dependencies for project org.apache.submarine:submarine-client:jar:0.4.0-SNAPSHOT: Failed to collect dependencies at org.apache.submarine:commons-runtime:jar:0.4.0-SNAPSHOT: Failed to read artifact descriptor for org.apache.submarine:commons-runtime:jar:0.4.0-SNAPSHOT: Could not transfer artifact org.apache.submarine:commons-runtime:pom:0.4.0-SNAPSHOT from/to apache.snapshots (http://repository.apache.org/snapshots): Connect to repository.apache.org:80 [repository.apache.org/207.244.88.140] failed: Connection timed out (Connection timed out) -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

How can we introduce the necessary dependency correctly? Or which online warehouse to use?
Looking forward to your answer，Thanks a lot!

hi @Languomao :-)
You are welcome to use submarine, you can compile subamrine according to this document. https://github.com/apache/submarine/blob/master/docs/development/BuildFromCode.md

I think this command should solve your problem:

mvn clean install package -DskipTests -Phadoop-2.9

When I import dependency, it will prompt

Downloading from apache.snapshots: http://repository.apache.org/snapshots/org/apache/submarine/commons-runtime/0.4.0-SNAPSHOT/maven-metadata.xml

But the download failed, when I go to http://repository.apache.org/snapshots/org/apache/submarine/commons-runtime/0.4.0-snapshot/ to view this path, this path does not exist, and then I switch to http://repository.apache.org/snapshots/org/apache/submarine/commons-runtime/0.3.0-snapshot/ ，but under this path, the file maven-metadata.xml does not exist。
Where can I find this file，thanks a lot。

mvn install ... will compile submarine locally and install it into your local mvn repository. Not downloaded from Apache's mvn repository.
If you cannot compile by executing mvn clean install package -DskipTests -Phadoop-2.9, i think, it should be caused by network problems.

Feel free to use users@submarine.apache.org too: https://submarine.apache.org/community/contributors.html

I have no problem downloading from repository.apache.org. Inclined to believe this is network issue. @Languomao let me know if there's still issue otherwise I'll close this issue.

Close this issue, if the problem is still exist, free to reopen. @Languomao
