Failed to generate JPA classes when using local ​mta archive builder

[gregorw]

Hello CAPM Java Experts,

I try to build my project https://github.com/gregorwolf/bookshop-java localy for XSA using the latest version of the mta archive builder downloaded from https://tools.hana.ondemand.com/#cloud (1.1.19) with the commandline:

java -jar /Users/gwolf/Downloads/MTABUILDER110_0-80002501.JAR --build-target=XSA build

Unfortunately this regurns the following error message:

[ERROR] Failed to execute goal com.sap.cloud.servicesdk.csn2jpa:csn2jpa-maven-plugin:1.4.3:csn2jpa (default) on project bookshop-srv: Failed to generate JPA classes -> [Help 1]

When I fun the generation manually with error logging on I see this output:

bookshop-java git:(master) ✗ mvn com.sap.cloud.servicesdk.csn2jpa:csn2jpa-maven-plugin:1.4.3:csn2jpa -DcsnFile=db/data-model.json -DoutputDirectory=/src/gen -e
