Install maven, Java 11.
Set JAVA_HOME to java 11
Make sure you set JAVA_HOME to be your java 11 installation. Then run:
mvn clean compile assembly:single
upload target/AWSLambda_DATA_Transform--SNAPSHOT-jar-with-dependencies.jar to AWS function. Tests are defined in the aws console.
Handler changes depending on the function e.g. for copying file function it should be set to:
uk.ac.cam.lib.cudl.awslambda.handlers.CopyFileHandler::handleRequest
When you're ready to make a release you can run the following
mvn release:prepare
mvn release:perform
This will tag a version in git and upload it to s3.
After this is done you should run git push and git push --tags to mae sure the
tags are pushed to the remote git repo.
After this version is published to s3 the AWS console can be used to update the lambda functions with the new version. Once tested a new fixed version of the lambda function can be created and the LIVE alias updated to use this version. This will make the live process use this code.
