I am trying to use checkstyles google_checks.xml with maven-checkstyle-plugin. If I use the google_checks.xml with the latest checkstyle intelliJ plugin everything is correct but when I try configurating it via maven-checkstyle plugin I get this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.13:check (default-cli) on project XX_XX_XX: Failed during checkstyle configuration: cannot initialize module TreeWalker - Unable to instantiate AvoidEscapedUnicodeCharacters:

My pom.xml looks like this:

Do you guys have some suggestions about what could be wrong?
fixed this by updating the checkstyle-dependency manually to the latest stable version:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<version>2.13</version>
<dependencies>
<dependency>
<groupId>com.puppycrawl.tools</groupId>
<artifactId>checkstyle</artifactId>
<version>${checkstyle.latest.version}</version>
</dependency>
</dependencies>
<configuration>
<configLocation>${checkstyle.file.path}</configLocation>
<failOnViolation>false</failOnViolation>
</configuration>
</plugin>
Maven checkstyle plugin uses checkstyle 5.7 (the first line of plugin description).
Checkstyle 5.7 does not have this check (see checks package on grepcode).
You need either to disable this check or to wait for official fix of MCHECKSTYLE-261.
I give a demo at
https://github.com/favoorr/Maven-Checkstyle-Multimodule-Use
Multi modules and use Google Chechstyle

Yes, you wont get that. Its just a basic, very simple maven project that eclipse creates for you, so that you can structure the project as you like.
You now have 2 options:
create all the structuring by yourself
Create a new maven project and instead of selecting select create a simple project, select from archetype, and from there you can you can select what you like (Ex: maven-archetype-quickstart ) according to what you like.
For more info on setting up maven project with arch type search in youtube. You will get a lot of video tutorials.
I'm trying to make a simple batch file with maven commands to execute the installation and execute the jar main class.
But the compile JAR does not have the dependencies and I get error
Exception in thread "main" java.lang.NoClassDefFoundError:
akka/actor/ActorSystem
This is my simple script
call mvn clean dependency:copy-dependencies
call mvn package
call cd target
call java -jar distributed-1.0.0.jar

What do I need here??
I think the easiest solution to create a runnable jar is to use Maven Assembly Plugin, or Maven Shade Plugin, or One Jar Plugin or even Spring Boot Plugin ( it's not weird if it works ). You can find some more details on how to use each one here.
These plugins are doing exactly you are trying to do with the 2 combined plugins that you have ( maven-dependency-plugin and maven-jar-plugin ).
I have a simple java project with on Junit test case that has the current architecture:
pom.xml
src/main/java/com/Example.Java
src/test/java/com/ExampleTest.java
The contents of pom.xml are as follow:
<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/maven-v4_0_0.xsd">

</plugins>
</build>
<dependencies>
<dependency>

To execute the tests I simply call mvn test from bash. This as expected will run the test. Now to my question:
specifying javagent outside of maven is simply done by specificity the -javaagent option. How do I do this within the maven framework such that when I execute mvn test the agent I specify is loaded? (i.e how do I add custom arguments that maven will pass to the 'java' command when the tests are executed)
Define the Surefire plugin in your POM and pass the JVM arg via Surefire's configuration.
For example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20.1</version>
<configuration>
<argLine>-javaagent:/path/to/javaagent</argLine>
</configuration>
</plugin>
For background: the test goal is bound to surefire:test by default (more details on default bindings here) so you have been already been running the Surefire plugin perhaps without realising it. The only change now is that you need to change the configuration of the Surefire plugin and this requires you to include it explicitly in your POM as per the example I showed above. You cannot run the test goal without using the Surefire plugin and you cannot tell Surefire to use a JVM arg without configuring the Surefire plugin to do so.
I am using maven jacoco plugin for code coverage. I decided to exclude some classes from jacoco coverage report. I found here, how to do it.
So my updated pom file looks like this:

So, when I am running mvn clean install command, I gets this error ():
Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.19:test failed: The forked VM terminated without properly saying goodbye. VM crash or System.exit called?
If I remove exclusion part, project builds successfully.
Can someone advise me how can I solve this issue?
issue is occur because maven-surefire-plugin is missing into your project pom.xml. you need to add this plugin into pom.xml, after adding need to update and rebuild the project and run it.
you can find the maven plugin below:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
</plugin>
</plugins>
you can refer higher version from 2.19.1.
I have found this solution on stackoverflow. Warning - Build path specifies execution environment J2SE-1.4

What and where should I add sth? I am using Eclipse on Windows 7. My version of java is: 1.8.0.25-b18 Words like plugin and Maven and JUnit are highlighted red. I would be grateful for help!
Try
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.4</source>
<target>1.4</target>
</configuration>
</plugin>
And then regenerate the Eclipse project with mvn eclipse:eclipse.
