Automatic Uploads via Travis CI
Travis CI can be used to automatically build a repository in response to code changes. To ease the maintenance of ImageJ update sites, we can use Travis to automatically upload the latest version of a site. This is done by creating a
.travis.yml file in your update site’s GitHub repository that does the following:
- Create a fresh ImageJ.app
- Build the update site’s repository and move the required artifacts (e.g.
.jars) to their intended locations in the ImageJ.app
- Upload the local update site state to your Wiki update site
As a starting point you can copy the following
language: java sudo: false cache: directories: - $HOME/.m2/ install: - mvn package script: - ./.travis-deploy.sh branches: only: - master
and this script
#!/usr/bin/env sh set -e # Define some variables export USER="Username" export UPDATE_SITE="/update-sites" export IJ_PATH="$HOME/Fiji.app" export URL="http://sites.imagej.net/$UPDATE_SITE/" export IJ_LAUNCHER="$IJ_PATH/ImageJ-linux64" export PATH="$IJ_PATH:$PATH" # Install ImageJ mkdir -p $IJ_PATH/ cd $HOME/ wget --no-check-certificate https://downloads.imagej.net/fiji/latest/fiji-linux64.zip unzip fiji-linux64.zip # Install the package cd $TRAVIS_BUILD_DIR/ mvn clean install -Dscijava.app.directory=$IJ_PATH -Ddelete.other.versions=true # Deploy the package # Deploy the package $IJ_LAUNCHER --update edit-update-site $UPDATE_SITE $URL "webdav:$USER:$WIKI_UPLOAD_PASS" . $IJ_LAUNCHER --update update $IJ_LAUNCHER --update upload --update-site $UPDATE_SITE --force-shadow jars/YOUR-FILE.jar
Don’t forget to replace
export USER="Username" export UPDATE_SITE="/update-sites"
by your informations.
Encrypting your password
To upload to your wiki update site, you will need to provide Travis CI with a
WIKI_UPLOAD_PASS environment variable, which should evaluate to the upload password of the Wiki account performing the upload. To do so securely, follow the instructions on the encrypting environment variables.
Note that when you run:
$ travis encrypt WIKI_UPLOAD_PASS=super_secret --add env.matrix
in your repository, the
.travis.yml will automatically be updated appropriately. You can simply commit and push the changes.
Travis CI is capable of building many languages besides Java. If you cannot use Maven with a
scijava.app.directory then you need to replace the following line of your
- `mvn clean install -Dscijava.app.directory="$(pwd)" -Ddelete.other.versions=true`
with a sequence of commands that will move your build artifacts to the appropriate
/plugins directory, as appropriate for your update site.
This is also true if you have custom scripts, macros, etc… if these files are not present in the correct locations of the local ImageJ.app, they will appear to have been deleted.
