Subject: Re: Where to put custom checksum for use as a layer?
You need to build your layer into a .jar file and then put that on Daffodil's
classpath.
If you're use the Daffodil CLI, you can add jars to the CLI classpath by
setting the DAFFODIL_CLASSPATH environment variable, for example:
export DAFFODIL_CLASSPATH="/path/to/custom/checksum/layer.jar"
daffodil parse -s schema.dfdl.xsd ...
If instead you're running TDML tests using SBT, a common technique is to
publish the layer jar to a local repository, then add it as a dependency to
the schema project that uses it. For example, you could do this to publish
locally:
cd /layer-project
sbt publishLocal
And add this to your schema project build.sbt file:
libraryDependencies ++= Seq(
"org.example" % "layer-project" % "1.0.0"
)
And then just run "sbt test" from the schema project. SBT will find the
locally published layer and automatically add it to the classpath when running
tests.
