Obviously you seemed to have changed the settings of the maven installation which went wrong based on the error message:
[WARNING] Some problems were encountered while building the effective settings
[WARNING] expected START_TAG or END_TAG not TEXT (position: TEXT seen ...ever maven must make a connection to a remote s
erver.\n |-->\n <s... @111:5) @ C:\programs\Maven\3\bin\..\conf\settings.xml
This means first clean up the conf/settings.xml file. Best is to use the default file which came via the installation. If you need to make modification do this in the users settings.xml $HOME/.m2/settings.xml
or on Windows C:/Users/UserName/.m2/settings.xml
Apart from that i don't know what you like to achieve by using something like this:
[WARNING] The POM for com.test:enforcer-dep:jar:${custom}:1.0.0 is missing, no dependency information available
