Using Spring Initializr in IntelliJ - other imports from say org.apache.zookeeper not working

I used a spring initializr project for creating a REST service (https://spring.io/guides/gs/intellij-idea/) and imported it in IntelliJ using Maven project.
That works fine. Unit tests run fine too.
Now, I added some code and imported another package (org.apache.zookeeper). IntelliJ does not seem to get that dependency. The compile error says (Error:(11, 28) java: package org.apache.zookeeper does not exist)
Moreover, I ensured that the pom.xml is updated and the effective POM as shown by Intellij lists the same package (scope - compile).
I checked that the Maven settings does not have anything odd, basically empty with the standard root tags.
Here is the POM -

Import a simple library from maven

I generated a Webservice Axis2 Client using a wsdl.
Most of the code works well I have a couple of errors missing dependencies.
org.apache.axis2.client.Stub
org.apache.axis2.description.AxisOperation
org.apache.axis2.description.AxisService
org.apache.axis2.AxisFault
org.apache.axis2.description.OutInAxisOperation
org.apache.axis2.context.MessageContext
... and a lot more
For example org.apache.axis.databinding is working
I have this axis2 dependencies on my pom.xml
But somehow I am missing dependencies.

You just forgot to enclose them within <dependencies></dependencies>. Just add these dependencies in your pom.xml and if you need more axis2 dependencies, just go the https://mvnrepository.com to look for more dependencies of axis2 and add them in your pom.xml, according to the version you are using.

NoClassDefFoundError: org/apache/spark/sql/DataFrame in spark-cassandra-connector

I'm trying to upgrade spark-cassandra-connector from 1.4 to 1.5.
Everything seems fine but when I run test cases then It stuck between the process and log some error message saying:

Thank you in advance!!
Can anyone please help me with this ?
If you need more info please let me know!!

Try to add dependency
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.10</artifactId>
<version>${spark.version}</version>
<scope>provided</scope>
</dependency>
Also make sure that your version spark-cassandra-connector is compatible with version of Spark you're using. I had the same error message even with all proper dependencies when was trying to use older spark-cassandra-connector with newer Spark version. Refer to this table: https://github.com/datastax/spark-cassandra-connector#version-compatibility

Maven embedder: Compiler dependency could not be resolved - No connector factories available

I have maven projects A and B. Project A uses maven embedder 3.2.5 and builds with it project B.
MavenCli mavenCli = new MavenCli();
mavenCli.doMain(new String[] {"package"}, "C:\\Users\\JohnDoe\\Desktop\\abc", System.out, System.out);
But I get the exception:
Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:3.1 from/to central (https://repo.maven.apache.org/maven2): No connector factories available
I looked into my local repository folder and there is indeed no plugin version 3.1. If I manually put it there the build is successful. But AFAIK maven automatically should download all necessary plugins. But it doesn't happen.

Adding these dependencies solved my problem
<dependency>
<groupId>org.eclipse.aether</groupId>
<artifactId>aether-connector-basic</artifactId>
<version>1.0.2.v20150114</version>
</dependency>

<version>2.8</version>
</dependency>
<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-provider-api</artifactId>
<version>2.8</version>
</dependency>

If you want to deploy, you also need this dependency:
<dependency
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3</version>
</dependency>

use these dependencies
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-embedder</artifactId>
<version>3.6.3</version>
</dependency>
<dependency>
<groupId>org.apache.maven</groupId>

</dependency>
<dependency>
<groupId>org.apache.maven.resolver</groupId>
<artifactId>maven-resolver-transport-http</artifactId>
<version>1.4.1</version>

use Apache Maven Artifact Resolver instead of Aether which is archived.

Maven build throwing error could not resolve dependencies

So i'm a front end developer that has no prior java experience and currently working on a project that uses backbone on the front end but java on the back and in order to get started on this project they supplied me with a build in which i was instructed to run 'mvn -Psystem-setup' ..
All seems to be going how it should until it throws an error saying ..
[ERROR] Failed to execute goal on project ee-api-validation:

I am completely lost and do not know what to do or how to fix this and have tried searching the internet for answers but everything i find and then try does not work. Can somebody please help me?

Try to execute mvn clean install and see if that solves the problem.

This could be a network problem resulting into incorrect resolution or your local proxy glitches.
Try
mvn -Psystem-setup clean install -U
And if doesn't help, remove artifacts manually from a folder $HOME/.m2/repository/org.jboss, after this
mvn -Psystem-setup clean install
And if this doesn't help, you may try downloading and installing the jar manually: How to manually install an artifact in Maven 2?

Seems like a network issue ... Make sure that you are not behind any firewall

You can try erase part of your .m2 library in your /home//.m2 or in window your user directory.
So maven can download again the jars
