Signed-off-by: Nigel Jones [email protected]

Description

Adds support to build a lightweight chassis for gradle builds.

Build by adding -PadminChassisOnly, for example

./gradlew -PadminChassisOnly build -x test -x javadoc

to build egeria with a cut-down admin chassis, and skipping test & javadoc.

Related Issue(s)

Fixes odpi/egeria-docs#675

Testing

Built with & without flag, and checked content of artifacts ie when set:

% jar -tf server-chassis-spring-3.15-SNAPSHOT.jar | grep spring | grep 3.15  
BOOT-INF/lib/admin-services-spring-3.15-SNAPSHOT.jar
BOOT-INF/lib/platform-services-spring-3.15-SNAPSHOT.jar
BOOT-INF/lib/spring-rest-client-connector-3.15-SNAPSHOT.jar

Release Notes & Documentation

Should be added to dojo documentation when happy (@mandy-chessell please indicate if you plan to do this)

Additional notes

This change replicates what we have with maven (though there we typically set via mvn with -D instead of -P - the implementation for gradle is more aligned with the normal way of setting gradle properties

In maven there is a conditional build for the connector configuration factory. I've implemented this. However the gradle build doesn't currently build an uber jar for this project, so the change makes no difference..... this condition could be removed. It's only relevant when building an uber jar since the dependencies are runtime only.

For the server chassis

• gaf wasn't in the gradle build at all. I presume it should be, so added
• 4 other dependencies looked as if they should have been excluded, but weren't. I have done so for gradle.

Please review. I can consolidate these changes with another commit

NOTE: I have not actually RUN a cut down platform.

This is good. I was surprised by the following libraries but realized they are the client-side libraries pulled in by the governance server services and so it is correct that they are there ...

asset-lineage-api-3.15-SNAPSHOT.jar
asset-lineage-client-3.15-SNAPSHOT.jar
asset-lineage-topic-connectors-3.15-SNAPSHOT.jar
data-engine-api-3.15-SNAPSHOT.jar
data-engine-client-3.15-SNAPSHOT.jar
data-engine-topic-connectors-3.15-SNAPSHOT.jar
governance-engine-api-3.15-SNAPSHOT.jar
governance-engine-client-3.15-SNAPSHOT.jar

Thanks for confirming. I will merge.

We do have options in future to strip more out, but we may also need to bundle some groupings to make it easier to assemble. That can be for another issue if we ever want to.
