-------------------------------
https://maven-repository.dev.java.net/nonav/repository/com.sun.jmx/jars/jmxri-1.2.1.jar
forwards to
http://download.java.net/maven/1/com.sun.jmx/jars/jmxri-1.2.1.jar
which ends up with:
Not Found. The requested object does not exist on this server.
This is mainly https://maven-repository.dev.java.net repository issue, but
because package from you central repository references this broken package it
is a bit of your issue now too ;-)
> log4j 1.2.15 points to nonfuctional maven-repository.dev.java.net packages

> Project: Maven Evangelism
> Issue Type: Bug
> Reporter: Jan Uhlir
>
> Log4j 2.1.15 dependency from central repository has dependencies linked to
> https://maven-repository.dev.java.net/nonav/repository - jmxri, jmxtools and
> java mail (and others?). These denpendencies are broken or the whole external
> repository is unaccesible by now.
> Is it even permitted to have "external" dependency for a package in central
> repository?
> I found it hard to find how to disable a repository (block a repository) so I
> am using this opportunity for a micro how to for unlucky ones like me.
> Troubled dependency definition:
> <dependency>
> <groupId>log4j</groupId>
> <artifactId>log4j</artifactId>
> <version>1.2.15</version>
> </dependency>

> Solution (1) - Disable repository (settings.xml).
> Note, it is much more tricky that it seems to be! It gave me hard time before
> I found out. Documentation should be improved here.
> 1) Tricky, you have to do it for releases and snapshots. There is no
> repository wide disabling option.
> 2) You have to provide not just same (failing) repository URL but more
> importantly the same repository ID as it is in ill referencig POM (log4j
> 2.1.15 in our case)
> 3) Blacklisting repository is something completely different then disabling.
> Not usable in this case (?). It is not ad hoc settable by user anyway
> OK, here is the code:
> <profile>
> <id>default</id>
> ...
> <repositories>
> <repository>
> <id>java.net</id>
> <!-- IMPORTANT!!! you have to use same ID as in
> affected POM otherwise it does not work -->
>
> <url>https://maven-repository.dev.java.net/nonav/repository</url>
> <releases>
> <enabled>false</enabled>
> </releases>
> <snapshots>
> <enabled>false</enabled>
> </snapshots>
> </repository>
> </repositories>
> </profile>
> Solution (2) - exclude the "external" sub-dependencies of log4j 2.1.15, like
> jmxri, jmxtools and java mail. And perhaps others. It takes more time to
> figure out what else "external".
> Solution (3) - the best one. Use version log4j 2.1.14 instead. It seems to be
> OK.
