Cannot run OpenJFX's non modular maven sample

Title is pretty self explanatory, I've downloaded the non-modular maven sample code for JavaFX from OpenJFX (from here) and I can't run it.
It compiles without any error but when I try to run it I get this error

Any idea is appreciated as I don't even understand the Cannot run program Java part.
I ran the javafx:compile then the javafx:run in Maven.

Ensure your JAVA_HOME environmental variable is set correctly. This will allow the javafx-maven-plugin to find the correct java command needed to run your application.
Follow this guide, choosing the relevant section for your OS:
Set JAVA_HOME on Windows 7, 8, 10, Mac OS X, Linux
Also, use the current version of the maven JavaFX plugin, 0.0.8, though that is not your core issue.

Maven build skips clean and validate phases

I am using IntelliJ IDE. My project is maven project. What is bothering me is that when for example choose "Install" phase from Maven Toolbar and click "Run Maven Build",
the clean phase is not executed:

So, as you see the first step taken is maven-resources-plugin:2.6:resources. From what I understood from maven docs is that when we specify a phase all previous phases are executed up to the chosen one. Per maven doc:
This command executes each default life cycle phase in order (validate, compile, package, etc.), before executing install. You only need to call the last build phase to be executed, in this case, install
Why is it skipping the clean and validate phases?
Edit:
I also have the clean phase in the Run Configuration section, but the result is the same:

Maven has 3 different builtin lifecycles
There are three built-in build lifecycles: default, clean and site.
install is part of the default lifecycle and there is no reason for clean to execute when you do install.
As to validate it has no built in binding as you can see here which means that it's not going to execute:
Furthermore, a build phase can also have zero or more goals bound to it. If a build phase has no goals bound to it, that build phase will not execute.

The default lifecycle does not include clean in it. Check the docs
Quote:
For example, the default lifecycle comprises of the following phases
(for a complete list of the lifecycle phases, refer to the Lifecycle
Reference):
validate - validate the project is correct and all necessary
information is available
compile - compile the source code of the
project
test - test the compiled source code using a suitable unit
testing framework. These tests should not require the code be packaged
or deployed
package - take the compiled code and package it in its
distributable format, such as a JAR.
verify - run any checks on
results of integration tests to ensure quality criteria are met
install - install the package into the local repository, for use as a
dependency in other projects locally
deploy - done in the build
environment, copies the final package to the remote repository for
sharing with other developers and projects.
Also, the validate phase is not associated with the default lifecycle of packaging .jar files.
Check the Default Lifecycle Bindings for JAR files at the bottom of the docs

Maven failing to assemble WAR - Java Heap Space Issue - Stanford Core NLP

So i'm getting this error when trying to Clean Install with Maven. I've attempted increasing MAVEN_OPTS with Xmx-512m or w/e it was called, similarly fiddled with Eclipse ini to increase heap space, but all of this to no avail, I keep getting this error:

I can't understand what is causing this, tried to find information online but can't seem to find this specific problem that anyone else is having. If anyone would be able to help i'd be very much appreciated.

Just figured it out,
Firstly, I had set MAVEN_OPTS incorrectly, I had them set as:
set MAVEN_OPTS="Xmx 512m"
After changing this to:
set MAVEN_OPTS="-Xmx512m"
You can also add this line into your profile (.profile, .bash_profile, etc) for this to be set in every terminal you open.
export MAVEN_OPTS="-Xmx512m"
And then went into the directory the project was in using CMD,
I ran:
mvn clean install -U
This seemed to do the trick and everything went successfully.
Hope this helps anyone else having problems!

I had the same issue running maven via ant from Jenkins on a Windows box.
The issue was how to pass the memory parameter. Here is the updated ant script showing how to pass the parameter "<jvmarg value="-Xmx1024m" />":
<target name="web.package" depends="init" if="warName">
<artifact:mvn mavenHome="${maven.home}" failonerror="true" fork="true">

Spring Boot - My unit tests are being skipped

I am migrating an existing project to boot. I created a brand new project using start.spring.io and copied over the source code, etc. Everything compiles, but when I do a 'mvn test' it compiles the classes but then only executes the default 'ApplicationTests' (created by start.spring.io).
Here's an excerpt from the maven output:
[INFO] --- maven-resources-plugin:2.6:testResources (default-testResources) # pendview ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.

What's even stranger is that if I pass '-Dtest=TestAuthController' then it does run that specific unit test:

(skipped output of AuthControllerTest for brevity)

What am I doing wrong? Does spring boot setup a surefire config that I'm not conforming to?
Any help would be greatly appreciated!

Spring Boot configures the Surefire plugin to run all test classes that have a name ending with Test or Tests but not starting with Abstract. You can see this configuration in the spring-boot-starter-parent pom. If your test class is named TestAuthController then it doesn't match this configuration. Renaming it to AuthControllerTest or AuthControllerTests should fix your problem.

Seems for me there is some issue with Maven surefire plugin, when it doesn't detect tests, if your test class name doesn't end with Tests suffix. :-)

Try this command in your console/terminal:
mvn clean install
But first navigate to directory of your tests.
If you wish to skip tests use this command:
mvn clean install -Dmaven.test.skip

It seems Andy's answer should be updated for Spring Boot 2.X. I can't see surefire config anywhere now. Probably there were too many complains about this convention.

building a scala-java-antlr project in maven results with ClassDefNotFoundError on runtime

I'm trying to port mustache.scala to scala 2.10, and make it built with maven with antlr3-maven-plugin instead of sbt. so far, i got this, and the code is compiled successfully. but at runtime, when i try to execute something simple like new Mustach("hello {{world}}!"), i get a java.lang.NoClassDefFoundError.
the weird thing, is that at first, i got the NoClassDefFoundError for Node class. i didn't understand why the java classes were'nt in the compiled jar, but i was eager to test if it worked. so i compiled just the two java classes with javac, and invoked the scala REPL as follows:
$scala -cp path/to/compiled/java/classes:path/to/jar-with-dependencies.jar
Welcome to Scala version 2.10.2 (OpenJDK 64-Bit Server VM, Java 1.7.0_21).
Type in expressions to have them evaluated.
Type :help for more information.
scala> import org.monkey.mustache._
import org.monkey.mustache._
scala> new Mustache("hello {{world}}!")
java.lang.NoClassDefFoundError: org/monkey/mustache/MustacheLexer
at org.monkey.mustache.Mustache.<init>(Mustache.scala:21)
at org.monkey.mustache.Mustache.<init>(Mustache.scala:32)
at .<init>(<console>:11)
at .<clinit>(<console>)
at .<init>(<console>:7)
at .<clinit>(<console>)
at $print(<console>)
...
so now i'm getting a NoClassDefFoundError on ANTLR output classes, so I see that not only the java files compile output was not packaged in the jar, but also ANTLR generated files. the scala code is depended on the java code as well as on the ANTLR generated code, so if the compilation succeeds, it must mean that at some point the java & ANTLR code was compiled succefully.
the relevant maven output is attached:
$ mvn clean install
.
. irrelevant output omitted...

buttom line, how do i get the compiled output from java files to be packaged in the jar along with the compiled scala code?

The scala compiler read the source *.java (explicit in your log), but it doesn't compile them. To compile your *.scala it can used *.java OR *.class.
The classes generated into target/generated-sources/antlr don't exist into target/classes. The compilation is not done by maven-compiler-plugin. Wrong use of includes : it's a filter not a way to add sources dir. Try to remove it : you will have compilation error like
.../MustacheLexer.java:[168,17] cannot find symbol
[ERROR] symbol : variable type
Sorry I don't know/search how to fix it.
