Maven can't find the plexus artifact in one of it's known repositories. Are there any repositories in the pom.xml? Have you set up your distribution correctly? Which repositories do you have in your settings.xml?
You might want to try and add maven central to your settings.xml (http://repo2.maven.org/maven2)

I am unable to run Maven configuration using my Eclipse IDE hosted on my Mac. It keeps on failing with the message that it is unable to parse a maven enforcer plugin file (see message below). There has not been any change to my Eclipse environment, my Maven project, my Maven configuration or my POM file. This was working fine 3-4 months back. Yesterday I cleaned up my entire repository (under $home/.m2) folder along with files under it and after that I am getting this error. It appears the maven download process is encountering issue. My eclipse plugin (m2e) uses version 1.10. I know it is a maven related issue but any help will be greatly appreciated

Thanks in advance for your help
As you probably know, Maven uses HTTP/HTTPS to fetch remote dependencies.
Sometimes the Maven repository that it uses is available only when you are connected to a VPN, or is otherwise sometimes unreachable. For example, your employer may have a private Maven repository that works when you're at work, but is unreachable at home.
Some Internet service providers (wrongly) do not return 404 error codes when you ask your browser to locate an unreachable URL. Instead, they return an HTML page with ads or other stuff on it that "help" you try to locate what you were looking for.
When you put all of these concepts together, if Maven uses HTTP to try to fetch a dependency from an unreachable Maven repository URL, it will fetch a page of HTML instead. In your case, you can see from your error message that there is something in that .pom file that looks like perhaps this is what happened.
The solution is to remove the containing directory from your local Maven cache (e.g. /Users/XXXXXX/.m2/repository/org/apache/maven/plugins/maven-enforcer-plugin/) and run Maven again when you know that you have a reliable network connection.
I want to use logback.slf4j in my Eclipse plugin, so I added it as a requirement to my MANIFEST.MF file:
Require-Bundle: org.eclipse.equinox.app,
org.eclipse.equinox.launcher,
...,
ch.qos.logback.slf4j;bundle-version="1.0.7"
Then I start the build with additional debug (mvn clean package -X) and in the output I can see that logback.slf4j is properly downloaded along with its dependencies:

As described in https://stackoverflow.com/a/45190630/301049
I managed to add a dependency on a fragment for a test plugin explicitly in pom.xml with the following target-platform-configuration plugin configuration:
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<configuration>
<dependency-resolution>
<extraRequirements>
<requirement>
<type>eclipse-plugin</type>
<id>org.acme.module.fragment</id>
<versionRange>0.0.0</versionRange>
</requirement>
</extraRequirements>
</dependency-resolution>
</configuration>
</plugin>
I am facing problems, while trying to run the NetworkAPIDemo example with reference to the htm.java-examples
If I try to run the code, I get the error:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I encountered the problem with both openjdk1.8 and oracle_jdk1.8 as well.
com.googlecode.matrix-toolkits-java.mtj.1.0.2 can be found in the .m2 folder (I'm using Maven with Eclipse).
I tried running it on two computers, it worked with one of the computers, but the same code did not work with another computer. I did not bother with the Cortico examples, so external libraries should not cause any problem. In the POM file, I specify only the dependency
org.numenta.htm.java.0.6.13
If I add the external libraries (which can be found in the libs folder), I get the error:
Exception in thread "main" java.lang.NoSuchMethodError: org.numenta.nupic.Parameters.set(Lorg/numenta/nupic/Parameters$KEY;Ljava/lang/Object;)V

I did not build the project from source, I only specified the dependencies in the POM.xml File. org.numenta.htm.java.0.6.12 can be found in the .m2 folder. I tried using 0.6.13 version of htm.java, but encountered the same problem.
POM.xml includes:
Specifying maven compiler to java 1.8
Specifying htm.java dependency
I am using Ubuntu 16.04 with Java:
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Can someone please give me an advice on what can be wrong? I copy-pasted the code from the github repository without modification.
Thank you for any help!
Problem solved!
If anyone encountered the same problem, you should add the library algorithmfoundry-shade-culled-1.3.jar to your project .
I want to run Tycho in an offline environment. Therefore, I mirrored a demo repository on GitHub and executed the command mvn clean install on a computer with internet access. The build succeeded, however when I try to run mvn -o install to install all dependencies in offline mode, I recieve the following exception:

Demo project which demonstrates offline build failure
The problem is reproducible always with the following steps:
rm -rf ~/.m2/repository
unzip demo-project.zip
cd mvn-demo-parent/releng
mvn clean install
Build succeeds
mvn clean -o clean install
Build fails because "Repository system is offline and no local cache available for http:// download.eclipse.org/releases/mars"

Following is the MANIFEST.MF of that bundle (Import-Package section):
Import-Package: my.other.module.package;version="[0.0,1)",
org.apache.commons.lang3.builder;version="[3.3,4)",
org.dozer;version="[5.5,6)",
org.osgi.service.blueprint;version="[1.0.0,2.0.0)"
Resolving the dependencies from the repository shouldn't be a problem, as launching the bundles from within eclipse works fine.
Interesting aspect: I'm working on Windows 7x64. On my coworker's pc with Linux it runs fine.
I'm not really sure where to start finding the error - the exception doesn't really give a hint, so I'd appreciate every tip. If you need further information, I'd be happy to clarify.
