Examples with CustomResourceDefinitionContextProvider cz.xtf.core.openshift.crd.CustomResourceDefinitionContextProvider used on opensource projects

Example 1 with CustomResourceDefinitionContextProvider

use of cz.xtf.core.openshift.crd.CustomResourceDefinitionContextProvider in project syndesis-qe by syndesisio.

the class CommonSteps method isProjectClean.

/**
 * Workaround for isProjectClean function from XTF. See issue: https://github.com/xtf-cz/xtf/issues/406
 * XTF cannot be update because it uses openshift-client 4.13.0 which contains kubernetes-model 4.11.2 where CRD was moved to the `v1beta1` .
 * Since Syndesis endpoints uses old kubernetes-model, the CRD is missing (`NoClassDefFoundError`)
 * When we let Syndesis endpoints to bring the old kubernetes-model with itself (remove <exclude> from parent pom.xml),
 * it causes undesired behaviour, e.g. portForwarding doesn't work correctly etc.
 * So we need to wait with bump xtf version until the Syndesis will contains newer kubernetes-model
 * <p>
 * This is implementation from XTF with workaround
 * To access to the protected methods, the JavaReflection API is used.
