Hello,
I am trying to build a Java project, and I uses Maven to manage the (java) package dependencies. I use fedpkg, as my goal is, someday, to publish it on Fedora Copr as a RPM package.
The project builds fine with Maven, but I am quickly stuck once I start with my specfile.
I am following the Java Packaging HOWTO, and I encountered the problem of missing dependencies.
This is a Maven error I get while executing ‘fedpkg --release f39 mockbuild --enable-network’
[ERROR] Failed to execute goal on project morganaxproc-iiise:
Could not resolve dependencies for project com.xml_project:morganaxproc-iiise:jar:1.4.1-SNAPSHOT:

Cannot access central (https://repo.maven.apache.org/maven2) in offline mode and the artifact co.paralleluniverse:quasar-core:jar:0.7.9 has not been downloaded from it before. -> [Help 1]
From what I understood, Fedora has some kind of ‘shadowing’ mechanism, with which Maven packages are mirrored inside Fedora’s build infrastructure, so builds can run independently from Maven: Maven packages have virtual provides in a format mvn(artifact coordinates)
So I added:
BuildRequires: mvn(commons-codec:commons-codec)
BuildRequires: mvn(co.paralleluniverse:quasar-core)
BuildRequires: mvn(nu.validator:htmlparser)
BuildRequires: mvn(co.paralleluniverse:quasar-actors)
BuildRequires: mvn(org.xmlresolver:xmlresolver)
BuildRequires: mvn(org.apache.httpcomponents:httpcore)
BuildRequires: mvn(org.apache.httpcomponents:httpclient)
BuildRequires: mvn(com.sun.mail:javax.mail)
BuildRequires: mvn(net.sf.saxon:Saxon-HE)
BuildRequires: mvn(com.fasterxml.jackson.core:jackson-databind)
BuildRequires: mvn(com.networknt:json-schema-validator)
BuildRequires: mvn(org.relaxng:jing)
BuildRequires: mvn(de.bottlecaps:markup-blitz)
BuildRequires: mvn(org.nineml:coffeefilter)
BuildRequires: mvn(org.nineml:coffeegrinder)
One ‘BuildRequires’ for each package.
After restarting the build, the result is better, but some packages are missing:
No matching package to install: 'mvn(co.paralleluniverse:quasar-actors)'
No matching package to install: 'mvn(co.paralleluniverse:quasar-core)'
No matching package to install: 'mvn(com.networknt:json-schema-validator)'
No matching package to install: 'mvn(de.bottlecaps:markup-blitz)'
No matching package to install: 'mvn(net.sf.saxon:Saxon-HE)'
No matching package to install: 'mvn(nu.validator:htmlparser)'
No matching package to install: 'mvn(org.nineml:coffeefilter)'
No matching package to install: 'mvn(org.nineml:coffeegrinder)'
No matching package to install: 'mvn(org.relaxng:jing)'
No matching package to install: 'mvn(org.xmlresolver:xmlresolver)'
Not all dependencies satisfied
Now, what should I do with that?
- Is it possible and wise to ask for these packages to be available as virtual provide?
- Any other ideas that I missed from the documentation?
