All java source files
src/test/java
All test java source files

All properties files. For example, application.properties

Though the executable jar file is getting created successfully but the properties file is missing in the jar file. I'm not sure what is the mistake here. Can somebody please point out the mistake or tell me if I missed something.
Thanks In Advance,
Varun Jain

I resolved it myself by creating the new project and copying the contents from this project to the newly created project.

jsonschema2pojo is not creating generated java object

I'm trying to use jsonschema2pojo to convert the FHIR schema to a java object. If I use this example schema then the generated java classes are create just fine, but when I use this Json Schema then nothing is created and I don't see any errors to understand why its not created. Can anybody help me understand where the failure is?

Maven is all about "convention over configuration" idiom. In order that maven-surefire-plugin will run your testcases it expects to find it under src/test/java, hence, you should follow the maven's standard directory layout and put all your test cases under src/test/java.

Any advice?

How about adding the dependency for hamcrest in your pom?
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-all</artifactId>
<version>1.3</version>
</dependency>
Also see this related SO question.

I've just added:
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-library</artifactId>
</dependency>
after
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
and it worked in my project.

Maven executable jar packaging vs Maven exec with Jackson not working

I need some help with trying to get an executable working. This is a tricky one and I've narrowed it down to the fact that something is different with the way that maven exec runs things and how either the maven shade plugin or the maven assembly plugin is packaging the files.
I'm building a REST service in Java with Netty and JAX-RS and use Jackson to translate from POJOs to JSON.
The server starts up correctly when executing either mvn exec:java or java -jar. But when making a request against the java -jar file, I get the following error:
Could not find MessageBodyWriter for response object of type: [Ljava.lang.Object; of media type: application/json
It seems like something isn't being packaged correctly, but I'm not sure what. Transitive dependencies are missing, maybe?
Here's my POM:

Maven shade is executed with mvn package.
Maven assembly is executed with mvn compile assembly:single.
Thanks in advance!
EDIT
I checked mvn dependency:tree against the output for mvn shade and for all intents, they look the same.
Output from dependency tree

The shade plugin configuration is missing the service transformer which merges the META-INF/services files used by the service discovery mechanism.
Here is an example:
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.example.helloworld.HelloWorldApplication</mainClass>
</transformer>
</transformers>

It's interesting because I asked myself the question yesterday, "why do I need an über jar?" And, as it turns out, I don't and probably shouldn't be using an über jar. Alexey correctly answered the question to solve the immediate problem, but I also wanted to post an alternate solution that I figured out for doing things a little bit differently.
Rather than using the shade plugin to build an über jar, I decided to create a standard jar and export all the dependencies needed to run my application. This means that I now use the Maven Jar Plugin to create my jar and the Maven Dependency Plugin to export the libraries. Here's what the build section of the pom.xml looks like:
<build>
<plugins>
<!-- For copying the libraries to the output directory -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
<!-- Create the executable jar -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.test.myserver.App</mainClass>
<useUniqueVersions>false</useUniqueVersions>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Since my output directory is target/, my jar is generated as target/myserver-1.0-SNAPSHOT.jar and all the dependencies are in target/lib/. The maven-jar-plugin also build the classpath and points them correctly to the lib/ directory, so I'm pretty much set. This also makes it easier in the future to replace individual libraries as they are updated, rather than uploading an entirely new jar.
Building the jar and copying the dependencies is simply mvn install from the command line.
