This repository aims at being a base for new Java repositories used in PDS. It guides developers to ease the initialization of a project and recommends preferred options to standardize developments and ease maintenance. Simply click the Use this template button ↑ (or use this hyperlink).

This is the XYZ that does this, that, and the other thing for the Planetary Data System.

It has useful information for developers and end-users.
Installation instructions here. Include any system-wide requirements (bres install, apk add, apt-get intstall, yum install, "CMMI" (configure, make, make install), etc.).
Basic usage instructions here. If possible, make it so your program works correctly "out of the box" as an executable .jar, or as a drop-in .war, etc., without any additional configuration.
An example log4j.properties file is in src/main/resources; mention how to customize it as needed—or delete it if it doesn't apply to your app.
Within the NASA Planetary Data System, we value the health of our community as much as the code. Towards that end, we ask that you read and practice what's described in these documents:
- Our contributor's guide delineates the kinds of contributions we accept.
- Our code of conduct outlines the standards of behavior we practice and expect by everyone who participates with our software.
We use the SemVer philosophy for versioning this software. Or not! Update this as you see fit.
To develop this project, use your favorite text editor, or an integrated development environment with Java support, such as Eclipse. You'll also need Apache Maven version 3. With these tools, you can typically run
mvn package
to produce a complete package. This runs all the phases necessary, including compilation, testing, and package assembly. Other common Maven phases include:
compile- just compile the source codetest- just run unit testsinstall- install into your local repositorydeploy- deploy to a remote repository — note that the Roundup action does this automatically for releases
The PDS uses Detect Secrets) to help prevent committing information to a repository that should remain secret.
For Detect Secrets to work, there is a one-time setup required to your personal global Git configuration, as well as several steps to create or update the required .secrets.baseline file needed to avoid false positive failures of the software. See the wiki entry on Detect Secrets to learn how to do this.
This package comes with a configuration for Pre-Commit, a system for automating and standardizing git hooks for code linting, security scanning, etc. Here in this Java template repository, we use Pre-Commit with Detect Secrets to prevent the accidental committing or commit messages containing secrets like API keys and passwords.
Pre-Commit and detect-secrets are language-neutral, but they themselves are written in Python. To take advantage of these features, you'll need a nearby Python installation. A recommended way to do this is with a virtual Python environment. Using the command line interface, run:
$ python -m venv .venv
$ source .venv/bin/activate # Use source .venv/bin/activate.csh if you're using a C-style shell
$ pip install pre-commit git+https://github.com/NASA-AMMOS/slim-detect-secrets.git@expSee Detect Secrets information above to setup your secrets baseline prior to proceeding.
Finally, install the pre-commit hooks:
pre-commit install
pre-commit install -t pre-push
pre-commit install -t prepare-commit-msg
pre-commit install -t commit-msg
You can then work normally. Pre-commit will run automatically during git commit and git push so long as the Python virtual environment is active.
👉 Note: For Detect Secrets to work, there is a one-time setup required to your personal global Git configuration. See the wiki entry on Detect Secrets to learn how to do this.
Thanks to GitHub Actions and the Roundup Action, this software undergoes continuous integration and deployment. Every time a change is merged into the main branch, an "unstable" (known in Java software development circles as a "SNAPSHOT") is created and delivered to the releases page and to the OSSRH.
You can make an official delivery by pushing a release/X.Y.Z branch to GitHub, replacing X with the major version number, Y with the minor version number, and Z with the micro version number. This results in a stable (non-SNAPSHOT) release generated and cryptographically signed (but by an automated process so alter trust expectations accordingly) and made available on the releases page and OSSRH; the website published; changelogs and requirements updated; and a new version number in the main branch prepared for future development.
The following sections detail how to do this manually should the automated steps fail.
👉 Note: Requires using PDS Maven Parent POM to ensure release profile is set.
Update pom.xml for the release version or use the Maven Versions Plugin, e.g.:
$ # Skip this step if this is a RELEASE CANDIDATE, we will deploy as SNAPSHOT version for testing
$ VERSION=1.15.0
$ mvn -DnewVersion=$VERSION versions:set
$ git add pom.xml
$ git add */pom.xmlUpdate Changelog using Github Changelog Generator. Note: Make sure you set $CHANGELOG_GITHUB_TOKEN in your .bash_profile or use the --token flag.
$ # For RELEASE CANDIDATE, set VERSION to future release version.
$ GITHUB_ORG=NASA-PDS
$ GITHUB_REPO=validate
$ github_changelog_generator --future-release v$VERSION --user $GITHUB_ORG --project $GITHUB_REPO --configure-sections '{"improvements":{"prefix":"**Improvements:**","labels":["Epic"]},"defects":{"prefix":"**Defects:**","labels":["bug"]},"deprecations":{"prefix":"**Deprecations:**","labels":["deprecation"]}}' --no-pull-requests --token $GITHUB_TOKEN
$ git add CHANGELOG.mdCommit changes using following template commit message:
$ # For operational release
$ git commit -m "[RELEASE] Validate v$VERSION"
$ # Push changes to main
$ git push --set-upstream origin main$ # For operational release
$ mvn --activate-profiles release clean site site:stage package deploy
$ # For release candidate
$ mvn clean site site:stage package deploy$ # For Release Candidate, you may need to delete old SNAPSHOT tag
$ git push origin :v$VERSION
$ # Now tag and push
$ REPO=validate
$ git tag v${VERSION} -m "[RELEASE] $REPO v$VERSION" -m "See [CHANGELOG](https://github.com/NASA-PDS/$REPO/blob/main/CHANGELOG.md) for more details."
$ git push --tags
From cloned repo:
$ git checkout gh-pages
$ # Copy the over to version-specific and default sites
$ rsync --archive --verbose target/staging/ .
$ git add .
$ # For operational release
$ git commit -m "Deploy v$VERSION docs"
$ # For release candidate
$ git commit -m "Deploy v${VERSION}-rc${CANDIDATE_NUM} docs"
$ git push origin gh-pagesUpdate pom.xml with the next SNAPSHOT version either manually or using Github Versions Plugin.
For RELEASE CANDIDATE, ignore this step.
$ git checkout main
$ # For release candidates, skip to push changes to main
$ VERSION=1.16.0-SNAPSHOT
$ mvn -DnewVersion=$VERSION versions:set
$ git add pom.xml
$ git commit -m "Update version for $VERSION development"
$ # Push changes to main
$ git push --set-upstream origin mainCurrently the process to create more formal release notes and attach Assets is done manually through the Github UI.
NOTE: Be sure to add the tar.gz and zip from the target/ directory to the release assets, and use the CHANGELOG generated above to create the RELEASE NOTES.
