System Requirements

Current software requires:

• Maven 3

Documentation

The documentation including release notes, installation and operation of the software should be online at https://NASA-PDS.github.io/pds4-jparser/. If it is not accessible, you can execute the "mvn site:run" command and view the documentation locally at http://localhost:8080.

Build

The software can be compiled and built with the "mvn compile" command but in order to create the JAR file, you must execute the "mvn compile jar:jar" command.

In order to create a complete distribution package, execute the following commands:

mvn site
mvn package

Operational Release

Run pre-build software

When new PDS4 Information Model is available, run the following script to download the latest IM and push to git.

$ build/pre-build.sh

pre-build.sh <dev_or_ops> <IM version>
     dev_or_ops - still in dev or released
     IM Version - e.g. 1D00

# For dev release of IM
build/pre-build.sh dev 1E00

For operation release of IM
build/pre-build.sh ops 1E00

Release with ConMan

For internal JPL use, the ConMan software package can be used for releasing software, otherwise the following sections outline how to complete these steps manually.

Manual Release

Note that GitHub Actions are enabled for the repository of this software so that automated SNAPSHOT and stable releases are available. Manual release instructions follow below.

VERSION=1.1.0
mvn versions:set -DnewVersion=$VERSION

git tag v$VERSION
git push --tags

Deploy Site to Github Pages

From cloned repo:

git checkout gh-pages

# Create specific version site
mv target/site $VERSION
rm -fr target

# Sync latest version to ops 
rsync -av $VERSION/* .
git add .
git commit -m "Deploy v$VERSION docs"
git push origin gh-pages

Update Versions For Development
