* do not swallow exception triggered inside SWA handling
--> write it to the log
The real change is in src/com/sap/piper/Utils.groovy
All the changes in the tests are dealing with mocking the echo method
used in the Utils class mentioned above.
This change add the support for running integration tests using the
recently introduced step mavenExecuteIntegration in
piperPipelineStageIntegration. In addition, capabilities to provide
temporary credentials to these tests is added using the
writeTemporaryCredentials step.
This change adds the groovy step writeTemporaryCredentials, in order to
avoid resolving configuration parameters within the piperPipelineStageIntegration
in the future.
For the integration tests functionality provided by the SAP Cloud SDK
Pipeline it needs be possible to configure a credential id pointing to
Jenkins credentials, which are then temporarily written to a file to be
available during the execution of the integration tests.
With the previous implementation solely in the TemporaryCredentialsUtils
class, it would be required to resolve the credentialId from the
configuratuion within the piperPipelineStageIntegration, once we fully
migrate the Cloud SDK integration tests stage.
