springframework.security package not found with starter-security dependency?

问题:

I'm using spring boot and spring starter dependencies for my project. I tried with spring starter security dependency in Gradle, but only security packages are not found in project. IDE is IntelliJ IDEA

My build.gradle file :

buildscript {     ext {         springBootVersion = '1.2.7.RELEASE'     }     repositories {         mavenCentral()     }     dependencies {         classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")          classpath('io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE')         classpath("org.springframework:springloaded:1.2.4.RELEASE")     } }  apply plugin: 'java' apply plugin: 'eclipse' apply plugin: 'idea' apply plugin: 'spring-boot'  apply plugin: 'io.spring.dependency-management'   jar {     baseName = 'hashfon-spring'     version = '0.0.1-SNAPSHOT' } sourceCompatibility = 1.8 targetCompatibility = 1.8  repositories {     mavenCentral() }   dependencies {     compile('org.springframework.boot:spring-boot-starter-data-jpa')     compile('org.springframework.boot:spring-boot-starter-data-rest')     compile('org.springframework.boot:spring-boot-starter-hateoas')     compile('org.springframework.boot:spring-boot-starter-jersey')     compile('org.springframework.boot:spring-boot-starter-mustache')     compile('org.springframework.boot:spring-boot-starter-thymeleaf')     compile('org.springframework.boot:spring-boot-starter-web')     compile('org.springframework.boot:spring-boot-starter-security')      runtime('mysql:mysql-connector-java')     testCompile('org.springframework.boot:spring-boot-starter-test')  } 

All libraries except security can be found in External Libraries...

One example of class in project:

import org.springframework.context.annotation.Configuration; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.*; import org.springframework.hateoas.*; import org.springframework.mock.*; import org.springframework.data.*; import org.springframework.security.*;  //cannot resolve symbol! /**  * I can import all packages from external libraries except security  */ 

PS. I tried with a lot of different release versions of spring-security-core and nothing happens.

After dealing with this issue multiple times I came across following solution which works for me 100%:

1. Go to File | Invalidate Caches
2. Delete folder where all dependencies are stored (~/.gradle/ for UNIX systems) - if it exists after invalidation
3. Restart Intellij IDEA
4. Reimport gradle dependencies by refreshing gradle:
