Building IDS app-store using docker.

[sriramsv2201]

Hello,
I am trying to build the IDS Appstore using Docker but always get the following error.

Caused by: org.apache.maven.project.DependencyResolutionException: Could not collect dependencies for project de.fraunhofer.fit:appstore:jar:3.0.0
5106.5 Failed to read artifact descriptor for de.fraunhofer.iais.eis.ids.infomodel:java:jar:4.2.7
5106.5 Caused by: The following artifacts could not be resolved: de.fraunhofer.iais.eis.ids.infomodel:java:pom:4.2.7 (absent): Could not transfer artifact de.fraunhofer.iais.eis.ids.infomodel:java:pom:4.2.7 from/to Maven
repository (https://repo1.maven.org/maven2/): PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

Can someone please tell me how to fix this?
Thanks
