Clojurians Log v2

Hello! Could somebody be so kind and explain to me why clj is trying to download a dependency from Maven Central when I told it to you our company repository (I assume M.C. is always used as a back up; but it doesn't seem it has even tried?!:

$ cat deps.edn
{:mvn/repos {"telia-aws" {:url "<https://my.company.net/component/artifacts>"}}
 :deps    {com.oracle.jdbc/ojdbc8       {:mvn/version "12.2.0.1"}}}

$ deps.exe -Sverbose
deps.clj version = 0.0.8
...

Refreshing classpath
Error building classpath. Could not find artifact com.oracle.jdbc:ojdbc8:jar:12.2.0.1 in central (<https://repo1.maven.org/maven2/>)

I think that error message just picks a repo and doesn't list all of them

It seems you were right! The problem turned out to be that my URL was wrong, it was missing a part of the path. The -Sverbose option was quite useless for troubleshooting this... :-(

Any idea why is clj trying to download a snapshot .jar from Central (where it isn't) when I have it in the local .m2 repo? Do I need to tell it to use the local repo?? > Error building classpath. Could not find artifact no.telia:clj-common:jar:0.1.0-20200507.122109-9 in central (https://repo1.maven.org/maven2/)

ls ~/.m2/repository/no/telia/clj-common/0.1.0-SNAPSHOT/clj-common-0.1.0-20200507.122109-9.jar                                                                                                                          
/Users/me/.m2/repository/no/telia/clj-common/0.1.0-SNAPSHOT/clj-common-0.1.0-20200507.122109-9.jar

no.telia/clj-common {:mvn/version "0.1.0-20200507.122109-9"} ;; a particular SNAPSHOT

SNAPSHOT versions are refreshed from external repositories at least once a day (by default, you can configure this in .m2 settings I believe)

it's maven behavior

Ah, ok. And if it fails to refresh, it just crashes without using the old version?

I found http://maven.apache.org/ref/3.6.2/maven-settings/settings.html#class_snapshots, I can try to set updatePolicy to never...

Hm, it seems that clj simply ignores my local .m2/repository. Now it is trying to download com.oracle.jdbc:ucp:pom:12.2.0.1 even though ~/.m2/repository/com/oracle/jdbc/ucp/12.2.0.1/ucp-12.2.0.1.jar exists...:

$ cat deps.edn
{:deps {com.oracle.jdbc/ucp {:mvn/version "12.2.0.1"}}}
$ clj
Error building classpath. Could not find artifact com.oracle.jdbc:ucp:jar:12.2.0.1 in central (<https://repo1.maven.org/maven2/>)
$ ls -lh ~/.m2/repository/com/oracle/jdbc/ucp/12.2.0.1/ucp-12.2.0.1.jar

did you put that jar manually in your .m2?

if so, you may be missing some metadata in your local cache that's triggering a lookup

deps doesn't currently expose this setting

So it doesn't take all of settings.xml into account, only parts of it (ie auth)?

it does not consider that setting, it does take more than just auth though

No, via mvn install-file . And it used to work...

https://clojure.org/reference/deps_and_cli describes supported stuff

specifically, also supports mirrors and proxies

and http properties

based on what I see here, I would expect it to find and use the jar in your local cache

you might want to clj -Sforce to make sure you don't have a cached classpath or something

I don't think that will matter since it seems to be building the classpath when it encounters the error, but just a good habit when diagnosing clj stuff

Ok, thank you!
