TestCordapp has now two implementations to clearly separate the two use cases it has in the Corda repo:
* TestCordappImpl which implements the revised public API of TestCordapp; namely that a TestCordapp instance references a real CorDapp jar on the classpath. This is either an external dependency jar in which case it’s taken as is and given to the node, or it’s a local gradle project in which case it’s compiled using the gradle “jar” task to generate the CorDapp jar. This approach means the jar has all the original CorDapp versioning information, which is important that it’s correct when testing. To this end, TestCordapp only needs to expose the ability to specify the app’s config. All the remaining properties have moved to CustomCordapp.
* CustomCordapp for creating arbitrary custom CorDapps, including specifying the jar’s MANIFEST values. This is internal API and only used for testing the platform. Technically this shouldn’t implement TestCordapp but does so to reduce the complexity of the driver and mock network.
* Split Workflow and contracts of Finance App into separate Cordapps, part 1 - content which is different between OS and ENT is still in contract Cordapp.
* Move CashSelection implementations to workflow module.
* Move CashSelection implmentations to workflow module.
* Move finance module to finance-flows, top level finance module is empty.
* Move finance module to finance-flows, top level finance module is empty.
* Updated build comment.
* Revert publication of combined (contracts and flows) corda-finance.jar (to maintain backwards compatibility with 3rd party cordapps dependent on finance)
* Added backwards compatibility clarification comment.
* Re-instate new cordapp metadata.
* Global rename of `finance-flows` to `finance-workflows` to follow adopted naming conventions.
* Addressed final review comments.
* Rename application to "Corda Finance Demo"
* Generation of original corda-finance jar from new sub-modules.
* Fixed and tested demobench with new split finance contract and workflow jars.
* Renamed finance sub-modules to contracts and workflows.
* Remove Michele!!!
* Minor fix to filtering logic.
* Align CorDapp configuration filename with workflows jar.
* Fix breaks caused by finance module naming changes.
* Final alignment between OS/ENT of finance contract code.
