Maven failed to download geotools dependencies

I want to use geotools in my java project, doing something like:
import org.geotools.data.shapefile.ShapefileDataStore;
Tried to add some geotools' required dependecies in my pom.xml file, like this:
<?xml version="1.0" encoding="UTF-8"?>

However, maven failed to download all the geotools dependencies, I checked the local repository geotools directory, no .jar file there. I followed the answer of this post, but still can't solve it. Could someone tell me how to get these geotools dependencies work?

There is no 19-SNAPSHOT in the repo.

Instead of using SNAPSHOT version , use release version like 19.4
You can know more about SNAPSHOT version from here

incompatible types: java.util.Optional<xyz.app.entity.Users> cannot be converted to Users (Springboot compilation error)

I'm getting an incompatible types error message at the following line in my spring-boot application:
RequestDO request = requestRepository.findOne(requestModel.getRequestId());
Users employee = usersRepository.findOne(request.getUsers().getId());
I have not experienced this error in this context before. My app has been running successfully since its first production build about one month ago.
Build failure:

I have made no code changes since I've last successfully re-built my project. This leads me to believe there has been a recent change in the springframework Maven dependency that has caused my code to break. Is it possible to test this by reverting to an older snapshot in my pom.xml? Also, what could be causing the error?

I had a similar issue using 2.0.0.BUILD-SNAPSHOT, so unless you're experimenting with some low-level spring boot features, change the version to 1.5.2.RELEASE

I had a similar issue and I still haven't got the answer.
But there is a solution. May be it help you.
Source option 5 is no longer supported

How to import the Confluence API with Maven?

I need to work with the Confluence API.
I work with Maven POM but I don't find how to insert the dependencies for the Confluence API.
Can you help me?
What I've already tried:
I need to work with the SpaceManager primaly.
I found this tutorial about managing the pom. So after the tutorial, my pom looks like the following:
<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">

<version>${confluence.version}</version>

</project>
The *** in the groupId is just to hide my package name of my company.
But also with this pom, I get the error The import com.atlassian cannot be resolved with this import:
import com.atlassian.confluence.spaces.SpaceManager;
So can you help me? Or please tell me what I should add to avoid downvotes, then I hope you see I really searched in the net and need help!

There are instructions how to work with atlassian maven repo Atlassian Maven Repositories and the repo URL is provided: https://maven.atlassian.com/repository/public
<!-- language: xml -->

<releases>

</repository>
If you're trying to add a plugin for confluence WIKI you'll probably need a dependency to:
<!-- language: xml -->
<groupId>com.atlassian.confluence</groupId>
<artifactId>confluence</artifactId>
( only once you add the atlassian maven repo to your pom.xml ) so full pom.xml will look like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- I had to add this section because activation-1.0.2.jar does not exist in public maven repo -->

<groupId>com.atlassian.confluence</groupId>
<artifactId>confluence</artifactId>
<version>5.2</version>
</dependency>
</dependencies>
</project>
This config works fine with version 5.2 and the SpaceManager class is accessible in your java code.

I'm not sure with Confluence API implementation you're using. You could try this:
<dependency>
<groupId>org.jvnet.hudson</groupId>
<artifactId>confluence-api</artifactId>
<version>1.0</version>
</dependency>
If you're using an implementation that doesn't support maven builds, then you'll have to add the transitive dependencies yourself.

In this case confluent.version is 3.0.0
<dependency>
<groupId>io.confluent</groupId>
<artifactId>common-config</artifactId>
<version>${confluent.version}</version>

"Cannot find class symbol" error in Maven for running Geo Tools

I am new to using Geo Tools and Maven. I'm following the tutorial and came across a specific error. The code I'm trying to run is available here.

And as I mentioned I am trying to run the same code provided in the above link.
The error I receive is:
line 122: cannot find symbol
symbol: class IntersectionBuilder
location: class org.geotools.grid.GridExamples
Is there a class missing? Any help would be highly appreciated.

I am fairly new to using geotools with maven myself and ran into similar issues recently. If I am not mistaken, gt-grid is an unsupported module. So you might need to download the source and build it in order to use it. I cannot seem to find the GridExamples class at http://svn.osgeo.org/geotools/tags/post-migration/modules/unsupported/grid/src/main/java/org/geotools/grid/

maven+gwt+eclipse

It appears I have a problem configuring maven in eclipse. i've installed through eclipse marketplace maven for eclipse and maven wtp and it eclipse won't recognize the first line of the POM. not to mention the <packaging>js</packaging> part
the error for the first line:

i've taken it from some online tutorial for building hibernate-gwt-maven project

It proably means you do not have javascript-maven-plugin-2.0.0-alpha-1.jar and aether-util-1.11.jar in your local or global maven repos.
You can find available javascript-maven-plugin and aether-util version at central repo here. Try downloading and installing them to your local m2 repo.
Note - They seem to be optional and I believe you can ditch the extension tag entirely from build tag. They might only help in compressing/cleaning up jquery js files ( ignore them for now )
