Subject: [PATCH] Build the core jar from the libraries JMEOS runs on, not from
 the tools that build it

The dependencies of jmeos-core are the libraries its code and tests import: slf4j-api 1.7.36,
which MeosErrorHandler logs through, is one of them, and maven-plugin-plugin,
jacoco-maven-plugin and junit are not. The two plugins are configured as build plugins, and the
tests run on junit-jupiter in the test scope; no source imports JUnit 4, Maven or JaCoCo.

Witness. The plugins and JUnit 4 sat in the compile scope, so the shaded jar carried Maven,
Aether, Plexus, JaCoCo and JUnit 4 along with JMEOS: 88 artifacts, 13 groups of overlapping
resources, and slf4j-api only as a dependency of maven-plugin-plugin.

Measured. Against the catalog and libmeos of MobilityDB 8a23781e4c with MEOS-API 8dddf59,
the shade step includes 25 artifacts and reports 3 groups of overlapping resources.
JMEOS-fat.jar holds no class of org.apache.maven, org.jacoco, org.codehaus.plexus,
org.eclipse.aether or JUnit 4, and 38 entries of org.slf4j. The suites run 106 and 1,810
tests, all passing.
