Issue adding MongoDB Java Driver as a Maven dependency - java

The title says it all really, my pom is shown below:
<?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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>CouncillorsApp</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.12.6</version>
</dependency>
</dependencies>
</project>
The following error is given:
"Dependency 'org.mongodb:mongodb-driver-sync:3.10.2' not found"
I'm using Java 14.0.2 and the latest version of IntelliJ


please read installation
you can try this
<dependencies>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.12.6</version>
</dependency>
</dependencies>


So after restarting IntelliJ the above code seems to work fine. I'm unsure of where the issue was, but the dependency is being found now without any changes to the pom.

Intellij not recognizing Dropwizard version dependency

I've started to create a java project using the dropwizard framework and maven. My pom.xml file looks like
<?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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.dexcane</groupId>
<artifactId>dexcane-backend</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<dropwizard.version>2.1.4-SNAPSHOT</dropwizard.version>
</properties>
<dependencies>
<!-- https://mvnrepository.com/artifact/io.dropwizard.archetypes/dropwizard-archetypes -->
<dependency>
<groupId>io.dropwizard</groupId>
<artifactId>dropwizard-core</artifactId>
<version>2.1.4-SNAPSHOT</version>
<type>pom</type>
</dependency>
</dependencies>
</project>
I'm following the dropwizard tutorial. When I hover over the "2.1.4-SNAPSHOT" dependency Intellij says "Dependency 'io.dropwizard:dropwizard-core:2.1.4-SNAPSHOT' not found ". Does anyone know what's wrong with the import? The tutorial says the current version of dropwizard is 2.1.4-SNAPSHOT.

You shouldn't add it with the type of pom as its packaging is jar.

Cant find where spring-web version defined in maven

I have a project, where I use spring-cloud-starter-stream-rabbit. But our devOps team asked me why I'm using spring-web. I've figured out that spring-web goes exactly from spring-cloud-starter-stream-rabbit. But there is no version defined:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
</dependency>
I've started to look in parent projects. But with no result.
pom hierarchy
I go from bottom to top:
spring-cloud-stream-binder-rabbit-core.pom
spring-cloud-stream-binder-rabbit-parent.pom
spring-cloud-build.pom
Surprisingly I cant find version there. I thought maybe this versions goes from other dependencies. Created project with single dependency like this
<?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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
<version>3.1.2</version>
</dependency>
</dependencies>
</project>
But mvn dependency:list showed:
...
[INFO] com.fasterxml:classmate:jar:1.3.4:compile
[INFO] org.springframework:spring-web:jar:5.3.4:compile
[INFO] javax.annotation:javax.annotation-api:jar:1.3.2:compile
...
Wow! Where is that secret place where maven gets version for spring-web? If you know please help.
Thanks for support!

Java: invalid source release: 9

I have created a maven project in IntelliJ, I downloaded the dependencies that I need and I can see there are no errors in the code.
I am still getting this error even though I have set Java 8 in project in Project Settings
This is what my pom.xml looks like:
<?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">
<modelVersion>4.0.0</modelVersion>
<groupId>multithreadedCalls</groupId>
<artifactId>multithreadedCalls</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.10</version>
</dependency>
</dependencies>
</project>

Just change java version on the second screenshot

That's how I made it work.
File -> settings and then went to this window and updated compiler version from the dropdown.

Spring method present in code, but not present in JAR

I would like to invoke that method:
https://github.com/spring-projects/spring-boot/blob/2.0.x/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/ErrorProperties.java#L73
But it's not available. It's not even present in decompiled code. But it should be, since JavaDoc says it's available from 1.3.0 version and it's public. My version is 2.0.0, I also checked 1.5.4. The link I gave is for 2.0.x and in GitHub it's still there. But in code it's not available, why?
POM:
<?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">
<modelVersion>4.0.0</modelVersion>
<groupId>test</groupId>
<artifactId>test</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
</dependencies>
</project>
Code:
import org.springframework.boot.autoconfigure.web.ErrorProperties;
public class Test {
ErrorProperties errorProperties = new ErrorProperties();
public Test() {
//Cannot resolve method getWhitelabel()
errorProperties.getWhitelabel();
}
}

That method is not in 2.0.0, nor in 2.0.3, but it is in 2.0.4 (the current latest version).
Change your pom.xml to:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.0.4.RELEASE</version>
</dependency>
</dependencies>
And it will compile.

How do you edit lifecycle phase without command line (Maven)?

I am trying to use Maven with my project in Eclipse and have the plugin installed but i get an "unknown lifecycle phase" error when i try to run the project. After doing some research it seems like i need to edit this configuration via command line. But apparently i would need to download the standalone maven installation to do this. Is there a way to edit the phase from Eclipse without command line?
