# NOTES ON BUILDING JAVA MODULES
#
# mvn is unable to resolve references to a plugin, if the same mvn
# program builds the plugin in the same reactor build.
#
# Therefore, we need to manually build all plugins first.
#
# The 'java' mode only builds the plugins.
# The 'default' mode also builds some modules needed by C++ code.
# The 'full' mode also builds modules needed by C++ tests.

# must install parent pom first:
echo "Downloading all dependencies. This may take a few minutes with an empty Maven cache."
mvn_install -N

# and build plugins first:
echo "Building Vespa Maven plugins."
mvn_install -f maven-plugins/pom.xml

# now everything else should just work with normal maven dependency resolution:
