I am able to build a jar for spark applications and java applications, but the same is not working for the snowpark applications. I would like to know, How to build executable jar from snowpark scala application and run from command line. I m able to build jar but not able to execute form command line
Below is my error

I have created a basic javafx project in eclipse using a maven archetype. When I run a maven install I get the following error. When I run the application in the IDE it works. When I try to run from the target folder it does nothing. Here is the error:

and package structure is as
You have to move all your resources and scala files to src\main\resources and src\main\scala. Shade plugin will not include your test resources and scala files. I have also tried shadedTestjar and it also does not work. The other option could be you use either
Maven Dependency plugin and move all dependency manually - Error prone and ugly
Use Assembly plugin - Not suitable
I have tried moving your resources and scala files in src/main and it has worked. Following is working pom content,

There are still file not found exception but I believe they are trivial to solve.
First learn about the Maven standard directory structure convention. Your main project source is now put under src/test/ instead of the correct src/main/, so they are treated as to be used in unit test. Therefore it will not be packaged.
I followed the testng sample of spring-restdocs 1.1.0.BUILD-SNAPSHOT. I am able to generate the adoc file through gradle. But when I am using the maven its not generating the doc files.
Mmy pom.xml has the following details:

Try to run using this command from your terminal:
$> mvn package
The generated files should be under /target.
generated snippets should be under /target/generated-snippets.
generated .html should be under /target/generated-docs.
Make sure you have your generated-snippets directory configured to /target directory on your test class:
#Rule
public RestDocumentation restDocumentation =
new RestDocumentation("target/generated-snippets");
I'm developing an Akka application using Maven. For testing, I use scalatest. When I run the tests with the configuration in application.conf, everything goes smoothly. But when I try to use custom files it just doesn't work (e.g. I have one common.conf and other files that include that one for adjusting time-scale in Jenkins and so on). I tried running the tests with mvn -Dconfig.file=/path/to/myenv.conf test and -Dconfig.resource=/path/to/myenv.conf test but no luck. I'm using Akka 2.4.0 and Scala 2.11.7.
P.S. Here is the configuration of the plugins in my pom.xml:

Thanks a lot!
Well, I actually found a way, just adding this to my scalatest maven plugin worked:
<argLine>-Dconfig.resource=/local.conf</argLine>
Is there a way to pass this externally to mvn test?
Following this Guide I ran the command
mvn assembly:assembly
and got the Build Failure of
Error reading assemblies: No assembly descriptors found.
I've looked at numerous questions on this, but to no avail.
From this post, I created a .xml with this inside:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">

</fileSet>
<fileSet>
<directory>src/main/resources/META-INF/services</directory>
<outputDirectory>META-INF/services</outputDirectory>
</fileSet>
</fileSets>
</assembly>
and included this in the pom.xml:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptors>
<descriptor>jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
</plugin>
but still no luck.
I'm pretty new to this as you can probably tell, how can I get this running?
~~EDIT~~
In the pom.xml I changed
<descriptor>jar-with-dependencies.xml</descriptor>
To
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
~~EDIT 2~~
pom.xml now contains this:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
~~EDIT 3~~
This pom.xml now works for me:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
For this to work, you need to create the file jar-with-dependencies.xml in src/main/assembly/ and this XML:
<descriptors>
<descriptor>src/main/assembly/jar-with-dependencies.xml</descriptor>
</descriptors>
i.e. you need to specify the path to the file and the convention is to put the files into src/main/assembly/.
To use the ones provided by Maven, you need to use the descriptorRef element instead (wrapped in a descriptorRefs).
Also don't put the descriptor inside of the execution element or mvn assembly:assembly can't find it anymore (since you specifically moved it to the mvn package target).
[EDIT] I followed the tutorial myself and there is an important point which you might have missed: You need to select the correct archetype. In my case, that was 5 but the order can change. So read the whole list and look for the string openimaj-quickstart-archetype or things will break.
