Can not import maven project to IDEA 14 - macos

I do $ mvn archetype:generate -DgroupId=demo -DartifactId=demo to create a maven project
then I want import the project to IDEA 14
then I choose Import project from external model and maven to next.
then there are some option we need to do , I just click next.
then it tells me to Select Maven projects to import
but there is nothing to show.
please tell me how to create a maven project and how to import it to IDEA 14 .

I always just Open project by selecting its pom.xml and it works well every time. Try this instead of Import Project.

I faced the same problem today. Tried many times. Finally, I got the solution that just to kill all the IntelliJ processes, restart it. It works. Seems some memory got corrupted, but please at least show some error message.

spring initializr: Cannot import org.slf4j.LoggerFactory for Gradle projects

I'm trying to learn how to build "Spring Web" web-applications using IntelliJ IDEA, and I'm encountering a very frustrating issue when I try to create a new project using "Spring Initializr".
For some reason when I choose to create a "Gradle Project", Java or Kotlin, I'm not able to import org.slf4j.LoggerFactory
If I manually add the import statement, it doesn't resolve, and if I try to get InteliJ to automatically add the import, it instead adds the following...
import com.sun.org.slf4j.internal.LoggerFactory
This satisfies the editor, but it won't compile. It errors with...
Symbol is declared in module 'java.xml.crypto' which does not export package 'com.sun.org.slf4j.internal'
If instead I create a "Maven Project", either Kotlin or Java, then it works as expected.
I'm keeping the other settings in spring initializr set to default values, Spring Boot=2.4.2, Java=11
IntelliJ IDEA says there are no updates available.
I've made various attempts to manual add the slf4j dependencies to build.gradle (for Java) or build.gradle.kts (for Kotlin), and nothing I've done has made any difference.
I've also tried various different options for Spring Boot and Java version, and again it has made no difference.
Update...
I've confirmed that it only happens on one of my computers, my primary development desktop computer. My laptop is working fine.
I can't find anything that's different between the 2 IDEA installations.
Things I've tried so far to fix it...
Invalidate Caches / Restart
Manage IDE Settings -> Restore Default Settings
Removing and re-adding JDK's
Uninstalling and re-installing IntelliJ IDEA
I've tried everything I can think of to fix this, but the problem persists.
Basically I can't use logging in any new Gradle Spring projects. It just won't load the org.slf4j library.
Update 2...
The nature of the problem isn't exactly what I thought it was initially. It turns out the code compiles and runs just fine with the correct import, but the IDE is reporting it as unresolved.
So it seems it's just an issue with the IDE's intellisense. This seems less serious, but it's still quite inconvenient having the editor incorrectly showing errors.
After identifying that the problem was just with the IDE editor intellisense, rather than with the code dependencies or project, I was eventually able to resolve it by closing the IDE, and then deleting the system folder "C:\Users<user>\AppData\Local\JetBrains\IntelliJIdea2020.3"
After restarting IntelliJ IDEA, the folder was re-created automatically and the issue resolved itself.

No next button when importing Maven projects in IntelliJ

I am trying to follow a tutorial on spring boot, first step is to import a maven project in intelliJ, generated by spring initializer, but when I try to do so, I have no next button in the import window, only "finish". And when I click on finish, it does not seem to detect packages. Any idea ?
Import from Maven dialog was replaced with single open action and now takes all the defaults without showing any additional dialogs with many various settings: IDEA-223880.
You may check with these guidelines.
Just type mvn install in the terminal.
or
Settings --> Build,Execution,Deployment --> Maven --> importing
Check the import Maven projects automatically
which will enable imports automatically.
Indeed all dependencies were resolved with maven build :)
Thanks guys !
Just to keep the question complete: In my case IntelliJ was unstable with JDK 12 and I had to use JDK 15. Another thing you might check is whether pom.xml is in the directory (in the past I have accidentally removed the file - type "maven" was displayed but after selecting "Maven" type there was only "Finish" and no "Next").

how do I fix type mismatch: #ExtendWith(SpringExtension::class) KClass -> Class in intelij?

I'm using intellij community 2018.2 and gradle 4.9 with kotlin 1.2.60
I've just downloaded a springboot2 pack from start.spring.io with kotlin/gradle support + web + h2 + jpa. I am following this official tutorial from spring.
gradle build and gradle test both work fine in command line.
In intellij though, I get the following error from the IDE:
Error:(9, 13) Kotlin: Type mismatch: inferred type is KClass<SpringExtension> but Class was expected
package org.ninrod.blog.blog
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.test.context.junit.jupiter.SpringExtension
#ExtendWith(SpringExtension::class) <-- RIGHT HERE
#SpringBootTest
class BlogApplicationTests {
#Test
fun contextLoads() {
}
}
here is the full source code of the sample: link.
How would one fix this in intellij so that the project compiles cleanly as in command line?
ps: here is a screenshot of the problem in intellij:
well, I uninstalled absolutely everything regarding java and then I installed everything from zero, removed all configurations, everything. Then it worked.
What you have is correct. I could not reproduce the error as shown in the screenshot below. And I was able to run your test without issue. So it is a false error. You can verify this by confirming the project builds via Gradle either from within IDEA of from the command prompt.
Try the following:
From the Gradle tool window, click the "Refresh all Gradle projects" button
From what I am seeing, and from my experience, I don't think think this will resolve the issue. But it is a quick hit and worth a wuick try.
It's possible the IntelliJ IDEA caches are corrupted. Go to *File > Invalidate Caches / Restart *. In the dialog window, click "Invalidate and Restart". After IDEA restarts and the project opens, wait for it to finish reindexing the project (watch the progress at the bottom). Once the reindex is done, see if the issue is resolved.
I suspect this will resolve the issue.
If the above does not work, then it's possible something is not configured correctly. Try recreating the IDEA project. Close the project, delete (or archive) the .idea directory and any *.iml files. Then import the project by selecting the build.gradle file. If you are not familiar with this, watch the "Working with Gradle in IntelliJ IDEA" video on the IntelliJ IDEA documentation page
Lastly, make sure you are running the latest version of IntelliJ IDEA (v2018.2), that was released two weeks ago. It is what I'm running. You using a lot of the latest and greatest tech (JUnit 5, Kotlin, Spring boot 2.x with Spring 5.x), so an older version of IDEA may have a problems. Finally, even though what you have worked for me, I'd recommend upgrading to the latest version of Kotlin (v1.2.60) in your gradle.properties
I do not get the error and can run the test:

Maven JavaFX Cannot find Main Class

I have some problems running my JavaFX8 Project with Maven. Here is the situation:
I create a Maven Java FX application within Netbeans (File --> New Project --> Maven JavaFX Application). Netbeans creates the packages and also creates a MainApp.java file.
Even if I don´t edit anything in this project, I get an error/warning within the properties.
Location: Right-Click Project --> Properties --> Run
Message: One of Run/Debug/Profile Project actions has been modified and the Run panel cannot be safely edited
The project can be built and run for some time, but after I create more packages, classes and stuff like that, I can´t run the application anymore.
It tells me, that it can´t find the Main class.
Message: Error: Could not find or load main class
I found some entries at stackoverflow and google, but none of the solutions seem to work for me.
I read this Topic for example.
One of the solutions is, to set the main class at the properties (Run), but all the fields are disabled. I also deleted the Cache, which didn´t solve the problem. I also checked the typing.
Some other sites stated, that it seems to be a bug, but they had older Netbean Versions. I updated my Netbeans version to 8.2 today.
The only solution at the moment is to create a new Maven JavaFX project and refactor the files to the new project. This works for a couple of hours but in the end the error occurs again.
Does anybody know a solution?
Use Run from the Project, not Run File from the main file. The latter can work on other setups, but not straight out of Maven.

Using Intellij + Maven to import libraries: Cannot resolve symbol

I have imported a library (JBox2D) using Maven in IntelliJ 13, for use in an android project. Maven didn't give me any error messages, so I assume the library was imported correctly.
However, as soon as I try use a class from the library, I get "Cannot resolve symbol". IntelliJ doesn't offer the option of adding an import statement, as it normally does.
How should I proceed?
Open the maven window and hit the reimport button (it's usually the first one on the toolbar). This will force IntelliJ to reimport your project based on changes in your pom.
Also, check the maven settings within IntelliJ and confirm that you're configured to use the same maven in IntelliJ as you're using on the command line.
If this doesn't work, then try to explain in more detail what you mean by your having imported a library with maven?
