Keypoint of Yaas local environment setup

[ghost]

This is very important

Step1

do use JDK1.8,

or else you will meet with this error:

Failed to execute goal com.sap.cloud.yaas.service-sdk:service-sdk-generator-maven-plugin:4.3.4:generate-service (default) on project OpeningEventDemo: Execution default of goal com.sap.cloud.yaas.service-sdk:service-sdk-generator-maven-plugin:4.3.4:generate-service failed: Unable to load the mojo 'generate-service' in the plugin 'com.sap.cloud.yaas.service-sdk:service-sdk-generator-maven-plugin:4.3.4' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: com/sap/cloud/yaas/servicesdk/plugin/generator/maven/ServiceGeneratorMojo : Unsupported major.minor version 52.0

Step2

also specify JDK 1.8 in your Eclipse:

or else you will meet with this error: No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK

Step3

Maven clean install: use this option to skip unit test

Step4

If you are using SAP corporate network, please set up proxy argument here:

Step5

Use the following content for Settings.xml when you are doing Yaas development. Do not forget to set proxy also in xml:
