com.sun.tools.xjc.maven2 giving No XSD files found even though xsd exist (java 11)

I am upgrading from java 8 to java 11. I'm attempting to use jaxb2-maven plugin to convert XSD files into java classes. when i run "mvn clean install" i get the below compile error
[INFO] Ignored given or default sources [xsd/dummy.xsd], since it is not an existent file or directory.

I have tried following the directions from these posts. I still got the same error
Maven jaxb2:xjc failing to generate code
the above post is mostly dealing with a lower version that is not compatible with most of my dependencies
https://artofcode.wordpress.com/2019/02/26/jaxb2-maven-plugin-2-4-and-java-11/
This post did not have any effect, both XSD were still not found

I was able to resolve this issue by using the below plugins
<build>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.15.1</version>

The problem is heroku currently using Java 8: Heroku Java versions
The indicator is this line:

I've encountered this problem when building maven application with target is Java 11 but running JDK is Java 8. I can't help with heroku since I haven't used it yet

At heroku you could really use the configurations in your pom.xml below,
please look carefully. :)
please check maven-plugin mentioned in pom.xml under <project>
I have something like this below.
...
<packaging>maven-plugin</packaging>
</project>
Futher more please check this plugin you could replace the below plugin code and modify as per your need. It can be added under build->plugins->THIS_PLUGIN

I am getting error when I am trying to do mvn package or mvn install on this project. The error is:
Failure to find org.codehaus.gmaven:groovy-all:jar:2.5.2 in http://myrepo:9090/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of Z-nexus-public has elapsed or updates are forced pom.xml /cockpit-repo line 1 Maven Configuration Problem
I tried to do mvn clean install -U and right click on project -> Maven -> update project with Update snapshots.
But nothing has worked till now.
Could anyone please help me regarding this?
Thanks in advance
PS: I tried mvn dependency:purge-local-repository clean install . It also gives error:

First try a forced update:
mvn clean install -U
If the forced update does not work there IS something wrong.
Check the following things:
Broken local artifacts - go to you local maven repository and search for the artifact and delete the folder. (in win usually under C:\Documents and Settings{your-username}.m2, in linux ~/.m2)
Is the artifact ACTUALLY on the repo, check spelling, version, everything!
Is the connection to the repo possible, watchout for proxy settings!

Maven add javadoc

I'm working in a Maven multimodule project and I'm not able to download javadocs for some dependencies. I'll describe my failed attempts:
I'm working with Netbeans so the first option was Right click in Dependencies -> Download Javadocs and some javadocs were dowoloaded but some other not.
Next option was to use mvn eclipse:eclipse but the result was the same (some javadocs were still missing). Also I saw that mvn eclipse plugin is deprecated
Last option was to use mvn dependency:resolve -Dclassifier=javadoc but the result is the same
I configured the maven-javadoc-plugin in my pom.xml but nothing happens. The configuration is the following:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.3</version>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
I don't want to use this option because implies a manual downloading. The third option gave me the following output:
[INFO] The following files have NOT been resolved:
[INFO] dom4j:dom4j:jar:javadoc:1.6.1:test
[INFO] org.jboss:jandex:jar:javadoc:1.1.0.Final:test

Any help is appreciated, also if someone tells me that there's no other option but to install the artifacts manually.
Thanks in advance.

Cobertura Checks Fail on Travis CI

In my Maven build, I use Cobertura to check that there is a certain minimal coverage:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.2</version>
<configuration>
<check>
<branchRate>100</branchRate>
</check>
</configuration>
<executions>
<execution>
<goals>
<goal>cobertura</goal>
<goal>check</goal>
</goals>
</execution>
</executions>
</plugin>
When running mvn install, this works fine. However, in Travis CI, the build fails because Travis first runs mvn install -DskipTests=true to get the dependencies. Obviously, when tests are skipped, there is no coverage, and therefore the whole build fails:
[ERROR] ch.trick17.betterchecks.fluent.StringCheck failed check. Branch coverage rate of 0.0% is below 100.0%
...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
...
[ERROR] Failed to execute goal org.codehaus.mojo:cobertura-maven-plugin:2.5.2:check (default) on project better-checks-core: Coverage check failed. See messages above. -> [Help 1]
Can I somehow configure Cobertura to skip the check if tests are skipped? Or is there any other solution, maybe on the Travis side?
Here is my .travis.yml file:
language: java
jdk:
- openjdk6
- openjdk7
- oraclejdk7
- oraclejdk8
script: "mvn install"

You can turn that of by using: install: true which skips the install step.

As an alternative to kmarbaise's answer, instead of completely turning off the install step, you can replace customize it so that it skips the Cobertura check:
install: mvn install -DskipTests=true -Dmaven.javadoc.skip=true -Dcobertura.skip=true -B -V
This way, the output of your actual build script will not be cluttered with output from downloading the dependencies and Maven plugins.
