Maven : Failed to execute Avro goal (Error compiling protocol file)

I have some Avro files using custom Logical Types. When I try to build my project using mvn clean install in order to generate automatically my Java classes. I've tried the following example of the implementation of Street type (https://github.com/markush81/avro-examples). I get the following error :
Failed to execute goal org.apache.avro:avro-maven-plugin:1.11.0:schema (schemas) on project atlas_v: Error compiling protocol file to project\src\main\java
Here is my pom.xml below :

I had this exact same error. My issue was that the .java source files that Avro was compiling to already existed and were owned by another user.

Separate build step for Java file - Maven

Within a larger Maven project, I have a Java file (AudioFileBuilder.java) that generates audio files from the Google Cloud Text-to-Speech service. It can execute from its own main() class; however, this file references an enumeration within the project (that other project source files depend on).
I am creating a fat JAR (JAR-with-dependencies), .exe file (Windows), and .app file (macOS) for the main project. I would like to exclude the AudioFileBuilder.java file AND the associated Google Cloud Text-to-Speech dependency in the JAR, exe, and app files. However, I still need the AudioFileBuilder.java file to run every time the project is built.
Here is a link to my project's current POM file (the project is open-source):

UPDATE:
I divided the project into two separate modules: "audio-builder" & "application" - as suggested by Welsh.
However, I have a Java enumeration ("Phrases.java") that both the audio-builder & application uses. The audio-builder needs this file to know which audio phrases are currently in the program, while the rest of the application needs this to load in said audio files & call the playback of these files.
So, this made me add the "audio-builder" module as a dependency for the "application" module. Since the Google Cloud dependency is needed at compile-time, this means that it is bundled in the generated JAR, app, and exe files.
These changes can be found here: https://github.com/hadi16/GamesForTheBlind/tree/Maven-Fixes

Thank you!

I would recommend that you split your projects into two sub projects, so you would have for example:
games-for-the-blind/
pom.xml
audio-builder/
pom.xml
application/
pom.xml
Then what you can do is have the audio-builder package output the required files into the application/resources directory and have it listed first in the main pom.xml file.
This would allow you to distribute the application resultant files that would not contain any of the details of the audio-builder project.

gwt maven plugin deploy to standalone tomcat not loading

I'm using the latest gwt maven plugin (https://tbroyer.github.io/gwt-maven-plugin/index.html) to compile a multi module GWT project and deploy it to tomcat 9. I am also using intellij 14 as my IDE. It's a client app only ie. no server/servlet. When I build via the IDE gwt plugin and zip up and deploy that output to tomcat my app works fine.
However, using the maven plugin, everything compiles ok and the contents of the war look fine to me. The war deploys ok to tomcat, but I simply see a blank page when I try to load it on my browser (latest chrome edition).
I'm running dev tools and jscript console and there are no errors being reported, network view, shows the content downloading ok. I've set break points in my nocache js files and stepped through it with no problems. Below is my pom. I'd appreciated any insight / help with this as it's been bugging me for days..

For anyone that is interested I got the maven build working on the multi module gwt project. See the following pom (dashboard) which is my app which inherits other modules.

I have to include the build resources entries on this pom and my inherited projects to manually include the public directory, not sure why, this appears to a quirk with the plugin.

Images not exported to executable jar file

I'm modifying Weka, an open-source Maven project, and my modifications are running perfectly on eclipse. However, when I export to an executable jar file, I get a null pointer exception, because it's not able to find the images I created and added to the project upon getImage() calls.
It seems that this is a rather common problem with jar files, so I tried using the URL method to load, but upon further investigation, when I look into the jar file with SecureZIP, the images(.png) that I added to the project are not even in the jar (however, the images (.png) that were in the original open source distribution were, despite the fact that all the images were in the same folder and of the same type (.png) designated by the build path in the source). Is there something I'm forgetting to do? Why are my images not exporting to the jar, but the other images in the folder are?
Library Handling is: "Extract required libraries into generated JAR".
Images are in src/main/java/weka/gui.

Groovy & maven - compile sourcesfrom src/main/groovy

I have been searching for few hours how to build .jar with maven.
Finnaly i got it.
But now i have to have sources in src/main/java.
How to 'include' src/main/groovy to my project?
I read solution here but I really don't want to change my pom.xml. I had so many troubles with this.
Here is my pom.xml

I tried with:
<sources>
<source>${basedir}/src/main/groovy</source>
</sources>
and
<build>
<resources>
<resource>
<directory>src/main/groovy</directory>
</resource>
</resources>
but still nothing.
I got :
Error: Could not find or load main class pl.jedro.Main

Finally got solution.
I added:
<sourceDirectory>src/main</sourceDirectory>
<resources>
<resource>
<directory>groovy</directory>
</resource>
</resources>
in <build> </build> section.
