SciJava Base POM
· This POM is a base which SciJava-based projects can extend to inherit helpful build configuration. It ensures that projects all use a compatible build environment, including versions of Maven plugins and Java itself. It does _not_ provide any dependency version management; see org.scijava:pom-scijava for that.
