latest opennlp-tools release
40ff5f2 is described below
commit 40ff5f28e114b968af8fd9cb79e99cc0a3afb32f
Author: Martin Wiesner <[email protected]>
AuthorDate: Sat Feb 4 10:52:56 2023 +0100
updates sandbox component 'opennlp-dl' to be compatible with latest
opennlp-tools release
- adjusts opennlp-tools to 2.1.0
- adjusts Java language level to 11
- updates several dependencies to more up-to-date versions to mitigate
several CVEs
- removes `nd4j-jblas` dep from 'opennlp-similarity' as was only required
for a transitive Spring dependency :-/
- adjusts code to changes in various dependencies
- ignores existing, non-working JUnit tests
- removes unused imports
- adds 'opennlp-dl' module to parent pom
- manages platform-specific DL4J dependencies via Maven profiles in
`opennlp-dl` and `opennlp-similarity`
-- supported: Win x86/x64, Linux amd64, MacOSX x64/arm64
-- unsupported: All Mobile platforms
