In the Udacity Developing Scalable Apps with Java course, I imported the Hello Endpoints project and tried to run it on Eclipse EE as instructed. However I got the following error message:
[INFO] ***********************************************************

How do I change the port number?
As you are building a Maven project, you can edit the pom.xml file and uncomment the <port>8080</port> value and set it to an unused port.

Using the jib-maven-plugin I'd like to build an image with mulitple tags. While mvn jib:build basically works fine, it "only" tags the image with latest.
My Maven pom.xml defines the following:
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>2.8.0</version>
<configuration>
<to>
<image>my-private-registry.org/my-image</image>
</to>
</configuration>
</plugin>
The docs show that one can use jib.to.tags in the XML to define a list of tags. However, I'd like to run the build step in a Jenkins pipeline, i.e. I cannot hard-code the tags in the pom.xml.
Is it possible to pass the list of tags when running the mvn command, e.g. by setting some -D parameters?
Use -Djib.to.tags=a,b,c.
$ mvn package jib:build -Djib.to.tags=a,b,c

On a Windows machine, I am running through the getting started tutorial here: https://www.scala-sbt.org/1.x/docs/sbt-by-example.html
I am able to start the sbt shell and compile but using the run command just hangs and I am forced to Ctrl-C to exit sbt.
Running scala against the JAR file directly also works as expected.
Sample output is the following:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

This is enough of an answer for my own purposes.
I was able work around this issue by adding a line to my build.sbt file. After adding ThisBuild / scalaVersion := "2.12.8" I was able to use the run command. Following the tutorial linked in the main question I would not expect to have to do this but perhaps someone could shed some light.

Any idea what's happening?
I've created an app with all the cartridges you mentioned and everything works fine to me. However there's a difference: my web.xml configuration file is somewhere else, at src/main/webapp/WEB-INF/web.xml. My bet is that wherever you're calling this you have the wrong path to it, as you can see on:
rm: cannot remove `/var/lib/openshift/XXX/jbossews//conf/web.xml': No such file or directory
FYI, typically, when you get the error Failed to execute: 'control deploy' it means that something in the process of deployment has gone wrong and it stopped, so that error message is not the actual error.
I manually created an empty file /var/lib/openshift/XXX/jbossews/conf/web.xml, and this solved the issue: the rm command ended successfully, the deployment succeeded.

How can I fix the above issue?
I got this error when I included the certificate file name in the certificatePath & didn't include 'certificatePassword' directive.
I hope this helps, but I'm fairly new to all this & fumbling around through various problems I'm having.
Currently I'm building it in Eclipse using the GWT plugin. I'd like to automate deployment to my development webserver using a script that does the GWT compilation from the command line.
I've followed the directions in the Running Via Maven section of the Getting Started page:
mvn -Phtml integration-test
But it tries to build all the versions, erring out on the Android build (which I'd prefer to skip at the moment) and throws a warning stating the html profile doesn't exist:

[WARNING] The requested profile "html" could not be activated because it does not exist.
How can I get it just to build the html version?
mvn clean package -pl core,html
This will only compile the core and html packages. If you only want html, you still need the core package.
The output will be by default in the target folder.
