Categorise failure types

[Vel1khan]

Build successful, partially reproducible

• Only pom and resource files reproducible, not jar (Maybe wrong JDK used?)
• Reproducible files belong to other packages in the same repo
  org.apache.maven.wagon,wagon-http-lightweight,3.5.0

Build successful, not reproducible

• Non-default build params?
• Wrong JDK used

Build fail

• Not built with Maven
• Correct JDK Toolchain not present
• Build command should include location of pom file (common in repos with multiple projects)
• Other packages/dependencies in same repository failing (we need to ONLY build our package) org.apache.atlas,impala-bridge,2.3.0
• (Maven Enforcer Plugin) Detected Maven Version: 3.6.3 is not in the allowed range [3.8, ) eu.maveniverse.maven.mima,context,1.0.3
• Some dependencies not in Maven Central
  com.adobe.dx,core,0.0.12
• Repository empty (project split into multiple smaller repositories)
  com.alibaba.lindorm,lucene-facet,8.9.0
• Failed to set up Docker container environment
  de.jflex,benchmark,1.9.0 failed because of a missing apt dependency but we can build it normally
• Builds correctly but other packages in same repo that come after it fail. But the .buildcompare should STILL be there!!?
• Failed to clone (possibly network downtime)
  org.simplify4u,pgp-keys-map,2021.07.02

Conclusions

• Ideally we tell Maven to build only our package (+ only required dependencies in the same repo)
• We might want to keep the build cache so that we can run diffoscope. Otherwise, we have to rebuild each project we want to inspect. Alternatiely, only keep the buildcache for non-/partially-reproducible packages to save space.

same as #86 we should decide about whether or not continue with this after looking at scores.
