Trouble importing java bcrypt library

I faced a problem with importing the Spring Security library.
Here is my main class:
package com.example.test.myfirstproject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
#SpringBootApplication
public class MyFirstProjectApplication {
public static void main(String[] args) {
SpringApplication.run(MyFirstProjectApplication.class, args);
}
#Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
return new BCryptPasswordEncoder();
}
}
And my pom.xml file:

When I'm trying to make a build in IntelliJ IDEA I get errors:
java: package org.springframework.security.crypto.bcrypt does not exist
java: cannot find symbol
symbol: class BCryptPasswordEncoder
location: class com.example.test.myfirstproject.MyFirstProjectApplication
I used autocomplete for method BCryptPasswordEncoder, so there shouldn't be a mistake. I also tried to change the place of security dependency in pom.xml file, but it also didn't help.
Thank you for your help!

#Component Scan Not Working with #Component In Spring Boot across jar and war

I am having a common jar file in spring boot application this way,
package com.acc.api;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#SpringBootApplication
#ComponentScan(basePackages = {"com.acc.api","service"})
public class ApicoreApplication {
public static void main(String[] args) {
ApplicationContext applicationContext = SpringApplication.run(ApicoreApplication.class, args);
for (String name: applicationContext.getBeanDefinitionNames()) {
System.out.println(name);
}
}
}
And components in this are,
package com.acc.api.core.utils;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
#Component
public class AccUtil {
#Autowired
private WebServiceEngine engine;
}
where WebServiceEngine is an third party api i cam calling.

IDE is not showing any errors, But I am getting below build errors when doing mvn clean install.

Can anyone help me in this regard?
Thanks in Advance.

When using Spring Boot the spring-boot-maven-plugin will repackage and restructure the generated jar file. This jar file isn't useable as a dependency in other applications. Instead you need to instruct the spring-boot-maven-plugin to repackage the jar and leave the original artifact (and publish both to your maven repository).
The Spring Boot Reference Guide has a special section on how to do this.
If your jar is only a dependency and not runnable/executable by itself then just remove the spring-boot-maven-plugin and generate a regular jar.

You have imported com.acc.api.core.utils.AccUtil class twice in StatusController class:
import com.acc.api.core.utils.AccUtil;
#Import({AccUtil.class})
remove one of them and try again.

Spring boot only scans for packages/jars that are a dependency.
Either way, compile-time scope, or run-time scope(provided).
So, if you try to scan jars that are not compile time dependend(default scope), e.g. because you integrate on a interface, you are still dependend on it runtime, so the componentscan can find the implementing class to inject.
If you wire e.g. #RestControllers, the application may be in another package/jar then your controllers.
And though you dont have a compile time dependency of the application package to the controllers, you still need to have the jar runt-time loaded. Otherwise, the controller will not be scanned and found run-time.

At my friend laptop it works without any problem.

Check the solrj jar version in dependencies.
Since spring boot is having a dependency of 4.10.4, new version doesnt get override. The old version does not have Cloud classes.
You can manually add
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>5.5.1</version>
</dependency>
You will have new version then.
