For some unknown reason, it appears that bad metadata exists in Nexus snapshots repository regarding our me.snowdrop:spring-boot-bom:1.5.7-SNAPSHOT artifact. This results in the current inability to deploy any further new snapshots with the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project spring-boot-bom: Failed to retrieve remote metadata me.snowdrop:spring-boot-bom:1.5.7-SNAPSHOT/maven-metadata.xml: Could not transfer metadata me.snowdrop:spring-boot-bom:1.5.7-SNAPSHOT/maven-metadata.xml from/to jboss-snapshots-repository (https://repository.jboss.org/nexus/content/repositories/snapshots/): Failed to transfer file: https://repository.jboss.org/nexus/content/repositories/snapshots/me/snowdrop/spring-boot-bom/1.5.7-SNAPSHOT/maven-metadata.xml.
