It looks for that artifact in the place defined in settings.xml. how do i change that. And I need the settings.xml since there are dependencies coming from jfrog, which are defined in the settings.xml
I even tried the force update -U, which doesn't work
mvn -U clean package -s settings.xml

Your settings.xml overrides the location for MavenCentral by using the central id.
If you don't want that, use a different id in the settings.xml.

I think you override the Url to the central maven repository.
Try to change the id in:
<pluginRepository>
<snapshots>
<enabled>false</enabled>
</snapshots>
<id>central</id>
<name>plugins-release</name>
<url>https://loyalty.jfrog.io/loyalty/plugins-release</url>
</pluginRepository>
The same for the repository

The problem is exactly what is described - spigot-api has a dependency on spigot and spigot has a dependency on spigot-api. Each one needs the other to exist to build, so there is no way to build this all from scratch.
You will need to fix these projects so you can build one without the other first - probably the API project should not rely on its implementation so try removing the dependency on spigot from the spigot-api project.

Error creating shaded jar: Problem shading JAR java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

I created fat jar(common-1.0-SNAPSHOT.jar) using maven shade plugin. It generated successfully. This common dependency include to new maven project and try to generate fat jar. But it given above error. I tried with different answers as exclude MANIFEST files. After excluding MANIFEST files it asked to exclude .class files in common.jar library.
Need I use any signing method to common library or is there any way to ignore this error.
Thank you.

java.lang.NoClassDefFoundError on running project with Java, but works when running with mvn exec:exec

I'm compiling and running some source code I got from a project called Structr (https://github.com/structr/structr). I'm able to run the program correctly with a maven mvn command but not using the JVM java command.
The compilation step goes well with maven clean install -DskipTests
On running the front-end (in the structr-ui directory), it goes well if using maven exec:exec but fails on java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui. I have some stack trace indicating java.lang.NoClassDefFoundError on org.structr.core.entity.AbstractNode and org.structr.core.EntityContext. What I find strange about this is that the maven pom.xml file in the exec entry we have

The mvn exec:exec statement looks equivalent to the java JVM statement. This question may be basically; What is maven doing differently than java, that in the maven case making the program run correctly?
Edit - additional maven and java debugging information
On mvn -X exec:exec, The output is given here http://roberthoff.com/files/mvn_exec_trace.txt
And on java -server -Dfile.encoding=utf-8 -XX:+UseNUMA -Xms1g -Xmx1g -classpath target/lib/*
;target/structr-ui-0.8.2.jar org.structr.Ui we have http://roberthoff.com/files/java_trace.txt

You have a valid question here, because according to the Maven documentation on the exec:exec goal you would need to have the <\classpath> stanza in your configuration in order to include the entire project module classpath.
However, it appears as though Maven is running the program with the fully (and properly) configured classpath for some reason.
In order to get to the bottom of the problem, I'd run Maven with the -X command line argument and carefully scan through the debug output until I found the exact command it runs. Then I'd try running it from the same directory, ensuring I am using the same Java installation and see if it works.

Notice the maven-dependency-plugin in the pom. It copies all dependencies during the package phase to target/lib folder and then they are on classpath. Following should work:
maven clean package -DskipTests
java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui
