Spring dependency not found

I'm very new to Spring, and also Maven. I'm following along with the book Spring Start Here because it seems friendly. The very first project asks us to add a spring-context dependency to a new project (using maven). I'm using the Intellij Idea community version to follow along, as suggested in the book. But on following the instructions to add the dependency I get an error: Dependency 'org.springframework:spring-context:' not found
Here is my pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">

</project>
I think the idea is to add spring dependencies one by one in order to see their purpose. The autocompletion in idea shows an error for the lines
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
I have already tried updating the maven>repositories in the ide settings but still get the same error.
Also, I found the page https://mvnrepository.com/artifact/org.springframework/spring-context which seems to suggest I have used the correct groupId and artifactId names
Edit: I just removed the empty version tag in the dependency.

maven usually requires the version tag to specify the version
Most cases where no version is specified are when the project inherits pom files
For example
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
Unlike npm and pip, it does not automatically select the latest version

Exception in thread "Thread-2" java.lang.NoSuchMethodError: kotlin.io.ByteStreamsKt.readBytes(Ljava/io/InputStream;) for PACT tests

I'm getting this kotlin exception when trying to run some PACT tests using Java and not sure how to fix it please.
Here the error :
Exception in thread "Thread-2" java.lang.NoSuchMethodError:
kotlin.io.ByteStreamsKt.readBytes(Ljava/io/InputStream;)[B
EDIT
I've updated my PACT dependencies to use more up to date versions, and I'm still getting the same issue, however only when I have the below dependency as part of it and not sure why.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>

This is my current pom:

And that's what I see when look for Kotlin after running maven dependency tree. The complete project can be found here.
Thanks very much.

A possible reason you are getting that error (I'm assuming) is because you are mixing major versions of the Pact libraries.
<pact.version>3.5.24</pact.version>
<pact-jvm-provider-maven.version>3.5.9</pact-jvm-provider-maven.version>
<pact-jvm-maven.version>3.5.24</pact-jvm-maven.version>
<pact.jvm.consumer.junit.version>4.0.10</pact.jvm.consumer.junit.version>
You have versions 3.5.9, 3.5.24 and 4.0.10. You should use the same major version.
Versions 3.5.x are mostly written in Kotlin (probably version 1.2.x), while version 4.0.x is written using Kotlin 1.3.x.
I'm not sure why Sprinboot is impacting things, but maybe a Spring dependency is also bringing in a version of the Kotlin standard library.
The best thing to do is use version 4.0.10 for all the Pact libraries, then run the Maven dependency tree plugin and check that versions of the Kotlin standard libraries that are being used.

dependencies from pom.xml not being resolved

I'm trying to create a maven project in intellij, to create a parser in antlr. Here is my pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<description>Trying to create a parser using ANTLR in Java, as facing problems with LLVM</description>
<properties>

<dependency>

<artifactId>antlr4-runtime</artifactId>

</dependency>
<dependency>
<groupId>org.apache.directory.studio</groupId>
<artifactId>org.apache.commons.io</artifactId>
</dependency>
</dependencies>
</project>
When I click on import changes, it loads for just 1-2 seconds then done. But if I try to import MapUtils from org.apache.commons.collections4.MapUtils it says it can't resolve common, although I added in <groupId>org.apache.commons</groupId> dependency.
I'm new in maven project creation and management.
So, what is the problem here and how can I resolve this problem ?
I studied some pom.xml and found a parent attribute. No idea how to configure that.

My Eclipse editor shows:
Project build error: 'dependencies.dependency.version' for org.antlr:antlr4-runtime:jar is missing.
Project build error: 'dependencies.dependency.version' for org.apache.commons:commons-collections4:jar is missing.
Project build error: 'dependencies.dependency.version' for org.apache.directory.studio:org.apache.commons.io:jar is missing.
None of the dependencies work, because it doesn't know which version of them you want.
Specifying dependencies without a version is something you do when you have a parent pom. You don't, so versions are mandatory.

You could try adding a specific version of antlr to your pom.xml. And if you are using the antlr plugin as well, make sure the version of antlr run-time you are using is the same as the built-in version of the plugin.

Assistance to Java Module: Module 'name' reads package 'javafx.beans'

Currently, I am trying to link a maven project with Java 9's module system however I keep getting the same error in every module.. (using Java 11)
Module 'common' reads package 'javafx.beans' from both 'javafx.base' and 'javafx.base'
I have been struggling with it for hours now. So far, I can conclude that every time I require javafx module it happens and it has probably something to do with duplication. In Project Structure (Intellij IDEA) two of each exists, version 11.0.2 (I have installed) and version 11.0.1 (from fontawesomefx). If I remove all the 11.0.1 versions, the implementation won't work.
module-info.java
module common {
exports common.services;
exports common.sidebar;
requires de.jensd.fx.fontawesomefx.commons;
requires javafx.graphics; // comment both javafx out, no error occurs except in the implementation.
requires javafx.controls;
}
pom.xml of common:
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>parent</artifactId> <!-- replaced original id -->
<groupId>me.name</groupId> <!-- replaced original name -->
<version>0.0.6</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>common</artifactId>
<dependencies>
<dependency>
<groupId>de.jensd</groupId>
<artifactId>fontawesomefx-commons</artifactId>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
</dependency>
</dependencies>
</project>
I hope this is enough information otherwise I can provide more.
Thanks!

So I found a solution today. It is all about duplication, so I searched to see if it was possible to exclude packages from a dependency and it is!
<dependency>
<groupId>de.jensd</groupId>
<artifactId>fontawesomefx-commons</artifactId>
<version>11.0</version>
<exclusions>
<exclusion>
<groupId>org.openjfx</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
</dependency>
I added the <exclusions></exclusions> tags to all another libraries with javafx as requirement and it worked!

Spring Boot SLF4J Error

I have been trying for several days to get the spring boot 15 minute hello world working. I keep encountering the following error:

I know this question appears elsewhere on the site, I have tried countless things and nothing works. I am using IntelliJ 2016.1.3, Java version 1.8.0._60.

I have tried maven clean from IntelliJ and no luck.
EDIT: Screenshot added to show everything being pulled into project.
Maven Dependencies
UPDATE: Completely uninstalled maven 3.3.9 and only have the built in maven from IntelliJ ultimate. Still not working, extremely frustrating. Over a week into this and can't get the 15 minute demo working.

You appear to have an incompatibility with versions of logging frameworks. See if replacing the spring-boot-starter and spring-web artifacts with spring-boot-starter-web helps, as per the current Getting Started guide.
Update
I was able to configure and build the Spring Getting Started guide down to the Add Unit Tests heading without error on Intellij Ultimate 2016.2 using its own embedded Maven 3, and on the command-line using Maven 3.1.1 and Java 8 (1.8.0_31-b13).
I found significant build errors and/or execution errors when I:
changed the Maven configuration in Intellij to use Maven 2
compiled with the spring-boot-starter and spring-web artifacts rather than spring-boot-starter-web.
I think your problem is a build configuration error. Whenever I get these, I go back to command-line to build and run just to be sure the problem isn't an artifact of some IDE bug.

I've run in the same problem, but got it solved by excluding logback-classic
So my pom now Looks like this:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>
If you're in Eclipse (idk, if IntelliJ has this Feature too) and look at the dependency hierarchy tab, you'll see, spring-boot itself implements multiple slf4j-apis.
Visualization of the dependency hierarchy filtered by "slf4j"
I know it may be too late for you, but your post was one of the first result by Google, so maybe it'll help someone else.

your pom lists java 8, but you said you are using java 6 for the project. make sure your project is pointing to a Java 8 ddk.
