I am trying to set up an Eclipe MicroProfile Application with Maven. I generated the archive with the MicroProfile Starter at start.microprofile.io, which generates the following pom:

I tried to start the application from Maven, as stated by the documentation: mvn package payara-micro:start, and Payara does not seem to find my packaged WAR file:
[2019-04-07T10:21:56.358+0200] [] [INFORMATION] [] [PayaraMicro] [tid: _ThreadID=1 _ThreadName=main] [timeMillis: 1554625316358] [levelValue: 800] Deployed 0 archive(s)
However, if I run this command from my projects' target folder, everything works as expected: java -jar config_api-microbundle.jar.
I would prefer bundling and starting the application with maven a lot, how can I achieve this?
Generated Payara Micro application from https://start.microprofile.io can be started using bundled Payara Micro uber jar with the following instructions :
The generation of the executable jar file can be performed by issuing the following command
mvn clean package
This will create an executable jar file demo-microbundle.jar within the target maven folder. This can be started by executing the following command
java -jar target/demo-microbundle.jar
To launch the test page, open your browser at the following URL
http://localhost:8080/index.html
And If you want to start Payara Micro instance from war, You may set deployWar property value to true:
<plugin>
<groupId>fish.payara.maven.plugins</groupId>
<artifactId>payara-micro-maven-plugin</artifactId>
<version>1.0.4</version>

The functionality of Parallel Deployment from Tomcat requires that the .war file name be in a specific format.
For example: If we have the version 1 of the project running and we need to hot deploy the version 2, it is needed that the .war name be "project-name##2.war".
We use in our project semantic versioning. So our versions are for example 5.31.6 .
When we deploy a new version through Tomcat manager we build the project using maven, rename the file name to project-name##053106.war and upload it to server. This process is manual and susceptible to errors.
Our version is set in pom.xml like this:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>br.com.group</groupId>
<artifactId>project-name</artifactId>
<version>5.31.6</version>
<packaging>war</packaging>
<name>Project Name</name>
<description>Project Description</description>
...
</project>
We set the final name in profiles, for example:
<profiles>
<profile>
<id>local</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<profilelabel>LOCAL</profilelabel>
</properties>
<build>
<finalName>project-name-local</finalName>
</build>
</profile>
<profile>
<id>production</id>
<properties>
<profilelabel>PRODUCTION</profilelabel>
</properties>
<build>
<finalName>project-name</finalName>
</build>
</profile>
</profiles>
My question is: With the examples above, how can I build the war file with the final name concatenated with version number without the dots and if possible with each "part" of version "str_pad"ed (5.31.6 becomes 053106)?
Using profile local: project-name-local##053106.war
Using profile prod: project-name##053106.war
You can use gmaven plugin to mangle project.version in any desired way and assign it to a property (all during initialization phase). Here is an example,
it handles versions with -SUFFIX part (to be safe, it handles the case of multiple dashes):
<build>
<finalName>yourProjectName-${paddedVersion}</finalName>
<plugins>
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>gmaven-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
println('Mangling project version: ' + project.version)
String[] versionParts = project.version.split("-")
paddedVersion = versionParts[0].split("\\.").collect { it.padLeft(2,"0") }.join()
if (versionParts.size() > 1) {
paddedVersion += "-" + versionParts[1..-1].join("-")
}
println('Padded version version: ' + paddedVersion)
project.properties["paddedVersion"] = paddedVersion
</source>
</configuration>
</execution>
</executions>
</plugin>
</plugins>

I have a question regarding how maven calculates the classpath during building. Specifically, what controls when the "target/classes" is used and when the "jar" from a repository (local/remote) is used.
I have a project on version 1.0.0-SNAPSHOT where the artifacts have NOT been installed/deployed so there is no "jar" in some repository (remote or local) to resolve them. I want to run "generate-sources" WITHOUT installing locally (no 'mvn install' run).
The structure looks like this:
parent-prj
parent-prj/sub-prj
parent-prj/gen-src-prj <--- This depends on 'sub-prj'
When I run "mvn -am -pl parent-prj/gen-src-prj generate-sources" in order to just generate some java files, it does not work:
[ERROR] Failed to execute goal on project gen-src-prj: Could
not resolve dependencies for project
mygrp:gen-src-prj:jar:1.0.0-SNAPSHOT:
Could not find artifact
mygrp:sub-prj:jar:1.0.0-SNAPSHOT -> [Help 1]
Using debug output and adding "dependency:build-classpath" I can confirm that maven ignores the presence of "sub-prj" in the reactor and looks for a "jar" somewhere which it can't find. Yet the project is printed in the reactor summary:
[INFO] Reactor Summary:
[INFO]
[INFO] parent-prj ..................................... SUCCESS [ 0.625 s]
[INFO] sub-prj ........................................ SUCCESS [ 0.018 s]
[INFO] gen-src-prj .................................... FAILURE [ 0.040 s]
The interesting thing I noticed is that running the compile goal works fine! This uses sub-prj/target/classes (as shown by dependency:build-classpath) and has no trouble generating the sources and even compiling them: "mvn -am -pl parent-prj/gen-src-prj compile"
So here are the points I want to understand:
Why does the compile goal work but the generate-sources doesn't work?
At what point does maven decide to use the output folder of previous projects on the reactor classpath instead of looking for a jar?
Is there a way for generate-sources to run directly as I want it EVEN WITHOUT having its dependencies resolved?
Regarding (3) my generation tool is a utility invoked by:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
The tool reads some XML in src/main/resources and generates Java files and does NOT need anything in its class-path (so there is no need for maven to resolve it).
Also note that I would be interested to understand (1) and (2) even if a solution for (3) is provided.

EDIT: Armed with the knowledge from the answers I have come up with this workaround that allows one to achieve the desired behaviour. I list the dependencies in a profile that is active by default, then use another profile to run generate-sources with no dependencies active, like follows:
parent-prj/gen-src-prj/pom.xml
<profiles>
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<dependency>
<groupId>mygrp</groupId>
<artifactId>sub-prj</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
</profile>
<profile>
<id>excludeDependency</id>
<dependencies>
</dependencies>
</profile>
</profiles>
To generate sources with above, use: mvn -PexcludeDependency generate-sources
Maven can reference only output generated in current Session (during currently executing shell command). It uses the most "mature" place to look for the "output":
If compile is run - the classes end up in the target/classes dir, thus other modules can reference that
If package is run - then target/*.jar is created and this jar file ends up in the classpath instead
If install is run - then jar file ends up in the local repository - which is what ends up on the classpath
So there are 3 factors that impede your task:
maven-exec-plugin requires dependency resolution (as pointed out by #mondaka)
Your module1 references module2
generate-sources is run before the compilation. Thus module2 is not yet prepared to be used as a dependency.
So if you want to do it your way - you'll have to run at least compile phase each time you use anything from the Default Lifecycle. Or you could write your own plugin that doesn't require dependency resolution.
This problem is related to an open maven bug:
https://issues.apache.org/jira/browse/MNG-3283
The issue says: "The problem only occurs when a plugin binds itself to the
generate-sources phase and has #requiresDependencyResolution".
I have checked that exec-maven-plugin Mojo have indeed requiresDependencyResolution = ResolutionScope.TEST. You can see that on https://github.com/mojohaus/exec-maven-plugin/blob/master/src/main/java/org/codehaus/mojo/exec/ExecJavaMojo.java
Then, your only option is to use compile or process-classes phases. This is a Major open bug from 2007...
In my POM.xml other the plugin configuration, i am not required to configure any dependenices to run the plugin. I would like to download dependent jars used by plugin(soapui-maven-plugin) from the repository into one single folder. I tried the command "mvn dependency:copy-dependencies", but no jars are copied. Is there any way to do it?

mvn dependency:copy-dependencies is only applied to current maven module only. It won't works on plugins. If you want to download all soapui-maven-plugin dependencies, you need to execute command from soapui-maven-plugin project. You can follow the following steps. I assumed you familiar with GIT CLI. If not, you need to manually download from https://github.com/SmartBear/soapui
git clone https://github.com/SmartBear/soapui
cd soapui/soapui-maven-plugin
mvn dependency:copy-dependencies
You can get list of dependencies in soapui/soapui-maven-plugin/target/dependency (total 82files)

If you get the above error, it means your maven jdk is version jdk.1.7 (u6 or earlier) which is not installed with javafx. Download newer jdk that comes with javafx at http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html . Remember change your maven jdk to this newer jdk.
If you want to use the dependency-plugin you could add the dependencies to the pom...and download with the depepndency-plugin...
It works right for me...

I have a Maven project with multiple modules and I'm trying to set it up so that module dependencies are automatically built to the correct lifecycle phase needed for building depending modules to the requested lifecycle phase.
In the example, the module plugin builds a Maven plugin, which is used to generate source code and is used by the module main. If I just try to use mvn -am -pl main compile, the module plugin is compiled but the process-classes lifecycle phase is not executed (which is necessary for a plugin to be usable). Compiling the module main then fails then with the following error:
[ERROR] Failed to parse plugin descriptor for example:plugin:1.0.0-SNAPSHOT (/Users/ims/Dropbox/IMS/Projects/PARITy_R4/codegen-test-simple/plugin/target/classes): No plugin descriptor found at META-INF/maven/plugin.xml -> [Help 1]
Is Maven, or a plugin for it, capable of resolving the dependencies of modules in a multi-module project and build them to stage necessary by other modules? And if so, how do I need to set up the project for this to work?

If you look at the reference documentation for the Maven lifecycle, you'll see that compile is before process-classes.
If you want this step to happen, you need to use mvn -am -pl main process-classes instead.
But I suggest that you always use mvn ... install - it also runs the tests and makes sure that the plugin which main uses is actually the one you think it should: Without install, the build will use an old/outdated version from the local repository (Maven will not magically determine "oh, there is a plugin in my reactor, I'll use that instead of the version from the local repo").
