I have an Eclipse Java project which has a class folder as dependency. This means that in order to run the app correctly I need to add that folder in the Java Build Path of the project.
In other words:
"Properties"->"Java Build Path"->"Libraries" -> "Add Class Folder"->folder with dependencies.
The Java project runs fine with this configuration either in Eclipse and in the exported runnable JAR file.
I rewrote the same project with Java Spring with the same configuration as above (the class folder dependency) and it still works fine inside the Eclipse IDE.
But, when I try to deploy the app with the command "mvn package", I got the following error:
[ERROR] COMPILATION ERROR :

This is exactly the dependency located inside the aforementioned folder and this means that in some way, the mvn package command is unable to read this folder, but Eclipse can without problems.
Maybe due to a POM misconfiguration?
In this case, here my POM file build section:
<packaging>jar</packaging>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
<mainClass>${start-class}</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
I also tried the following:
mvn clean package spring-boot:repackage
mvn install
but I got the same error message.
So, how to tell MVN to also "consider" that folder to build the project?

maven checkstyle plugin is telling me that it's using sun_checks.xml by default:
INFO] There are 5 errors reported by Checkstyle 8.29 with sun_checks.xml ruleset.
I mean, I've not located any sun_checks.xml into my project in order to tell checkstyle plugin to use this file.
So, I guess, plugin has available this file by default.
According to documentation, plugin has available two check rulesets by default: sun_checks.xml and google_checks.xml.
I've tried to change it:
<reporting>

<plugin>
<groupId>org.apache.maven.plugins</groupId>

<version>${checkstyle-plugin.version}</version>
<configuration>

</configuration>
</plugin>
</plugins>
</reporting>
After performing mvn checkstyle:check goal, it's telling me that it's using sun_checks.xml instead of google_checks.xml:
$ mvn checkstyle:check

Any ideas?
You are using the google_checks.xml under <reporting> tag. You can keep it like this but repoting tag as maven.apache.org says: A plugin is actually not a report plugin in itself. But one (or several) of its goals or Mojos may be specialized to be invoked by maven-site-plugin, typically during the site build life cycle.
if you want to use mvn checkstyle:check goal you need to also have:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<version>2.17</version>
<executions>

I am working on a JavaFX project using Maven which requires the JavaFX on screen keyboard enabled. I am trying to achieve this by using the following JVM options.
-Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.virtualKeyboard=javafx
The corresponding POM sections are as fololows.
<!-- Property Definitions -->
<properties>
<jvm.options>-Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.virtualKeyboard=javafx</jvm.options>
</properties>

<configuration>

<compilerArgs>
<compilerArg>${jvm.options}</compilerArg>
</compilerArgs>
</configuration>
</plugin>
The source results in a maven build failure with the following error.

I even tried a working example project from several sites,
such as
http://examples.javacodegeeks.com/enterprise-java/maven/create-java-project-with-maven-example/
http://www.mkyong.com/maven/how-to-create-a-java-project-with-maven/
but I got same error.
I unzipped maven at C:\apache-maven-3.3.3 and created environment variable MAVEN_HOME as same path.
What is the problem?
====================================
EDIT: Here is the result
Well.. I set MAVEN_HOME, not M2_HOME because tutorial what I found said to set it only...
Of course, echo %MAVEN_HOME% shows
C:\apache-maven-3.3.3
is it wrong?
I added %MAVEN_HOME%\bin to PATH variable, but it did not work too.
And, I'm using eclipse
=====================================
EDIT2: Here is full log. I used goal 'clean exec:java -e -X'
It was too long, so I uploaded to my blog here.
And note that I changed repository folder from C:\Users.....m2 to new local repository folder C:\apache-maven-localrepository
https://arincblossom.wordpress.com/2015/06/15/error-logs/
=======================================
EDIT3: I changed maven-compiler-plugin setting like this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<verbose>true</verbose>
<fork>true</fork>
<executable>${env.JAVA_HOME}/bin/javac</executable>
<compilerVersion>1.5</compilerVersion>
<!-- <source>1.8</source>
<target>1.8</target> -->
</configuration>
</plugin>
It prevented me from having error from mvn -e compile exec:java but I can't run with mvn exec:java -Dexec.mainClass="com.jadex.qna.QNAProject.App"
=================================
EDIT4: OK, I'll try from the bottom, and post again. Thanks for your sincere helps.
======================================
EDIT5
I reset all the sequences... re-installed eclipse, maven.. and re-created projects... but nothing worked...
I changed eclipse settings to fix JDK path to installed jdk path, not JRE path. then I found that 'mvn -e clean compile exec:java' is working, but I want to just 'mvn clean exec:java' work. It does not work at all.

This issue happens, when it is not compatible with eclipse too.
Try this
mvn clean install eclipse:eclipse
Vote up, if it works to help fellow members
The error log which you posted says the following:
java.lang.ClassNotFoundException com.jadex.qna.QNAProject.App
So it clear what the root source of the error is. You are trying to execute the main() method of a class whose class file Maven cannot find. As this SO article discusses, you can try explicitly compiling first, then executing after the class file has been generated:
mvn -e compile exec:java
mvn exec:java -Dexec.mainClass="com.jadex.qna.QNAProject.App"
I ran into this same problem, it was caused by a port conflict.
my tomcat server tried to start on port 8080 but i already had a binding for it.
netstat -anto will show you port bindings 0.0.0.0:8080 or similar and it's PID this will help you determin what process is already running the port bidning, either change it in your timcat server or whatever process is using the bidning. Could be caused by an IIS, SKype or similar.
I have installed the m2e plugin for Eclipse and used it to create a simple archetype. I wrote a small test driver and am trying to build the project (via Maven) and compile my Java sources into class files.
I go toRun >> Run Configurations and create a New Maven Build. I name it and set its base directory to be my project root.
When I try to select Goals it doesn't see any and so I can't add/specify any. I click the Run button. Here is my console output:

A few things:
What should my artifactId, groupId and version be if this is the (standard) Maven compile phase?
Is this the correct way to launch a Maven build (through Run Configurations)? In Ant there is a plugin that lets you see all of the targets defined in your build.xml; I see no such analog in Maven/m2e.
Why does something as simple as compile require plugins? One would think this would be a standard part of any build tool.
You don't need to put anything as you are using all the defaults settings of the maven compiler. If you really want to specify it you can do it this way:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
