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:

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.

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

On line 73,66 i have used command String.join(); What can I do to fix this? I created application with Tomcat 7 in OpenShift.

String.join added in Java8. You are using Java 7.
Follow this tutorial, and
"export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0"
in your "action_hooks/start" script. See action hooks documentation

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"

</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

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:

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

How to setup a maven project in Intellij IDEA 12

I have problem importing a maven project which was created by Netbeans into the IDEA 12. The dependency artifacts writen in the pom doesn't work. It told me that "cannot resolve symbol 'springframework'" on "import org.springframework.xxx;". When I runs it, it says that org.springframework.xxx doesn't exist.

When the pom.xml file is available in your project, you can generate the files needed by IntelliJ idea project by running this command:
mvn idea:idea
Check out more options and details here:
http://maven.apache.org/plugins/maven-idea-plugin/usage.html

If the project runs on the command line (mvn clean install) the chance is like 100% it will work in IntelliJ 12 too :-)
After File -> Project Import -> From external Maven Model you should see the modules.
What I would check in the IntelliJ settings is the location of the maven home directory (File -> Settings -> Maven) and the settings.xml files it reads (or does not read).
The mvn install within the IDE should not differ from what happens on the command line. If it does it would compare mvn help:effective-settings output from the command line and from IntelliJ (maybe also from Netbeans).
If you just dont see all modules right click on the parent-pom.xml and choose maven -> reimport. To resolve the dependencies you have to execute an install once. It does not automatically resolve dependencies in all cases.

Had the same problem,
you can simply Right+Click on the code and go Maven->Reimport and it should do the trick

I used mvn -U idea:idea to generate the IntelliJ specific files with dependencies downloaded.
