IntelliJ Spring Boot - "Cannot resolve symbol 'JmsTemplate'" when creating a bean

Question

IntelliJ has been throwing "Cannot resolve symbol 'JmsTemplate'" for the past few days, when creating a jmsTemplate bean.

Here's my TestConfig.groovy file the error is thrown.

`

package automation.test

import org.apache.activemq.ActiveMQConnectionFactory
import org.springframework.beans.factory.annotation.Value
import org.springframework.boot.SpringBootConfiguration
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.ComponentScan
import org.springframework.jms.core.JmsTemplate

import javax.jms.ConnectionFactory

@SpringBootConfiguration
@EnableJms
class TestConfig {
    @Value('${activemq.host}')
    private String brokerUrl

    @Bean
    public ConnectionFactory connectionFactory() {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
        activeMQConnectionFactory.setBrokerURL(brokerUrl)
        return activeMQConnectionFactory
    }

    @Bean
    public JmsTemplate jmsTemplate() {
        JmsTemplate jmsTemplate = new JmsTemplate()
        jmsTemplate.setConnectionFactory(connectionFactory())
        jmsTemplate.setReceiveTimeout(10000)
        return jmsTemplate;
    }
}

`

Here's my dependencies in build.gradle

dependencies {
    implementation "org.springframework.boot:spring-boot-starter-data-jpa:2.2.6.RELEASE"
    implementation "org.codehaus.groovy:groovy-all:3.0.9"

    implementation 'com.mashape.unirest:unirest-java:1.4.9'

    implementation 'com.google.code.findbugs:jsr305:3.0.2'
}

Here's the stacktrace.

I've tried to resolve this using multiple techniques I managed to find online with no effect.

1. Delete the .idea folder and re-launch the project.
2. Invalidate caches and restart.
3. Re-installed the JDK and added it to the path
4. Made sure the correct SDK is set in the File->Project Structure settings.
5. Checked the Language Level of the modules and the Java Compiler.
6. Tried to add the @EnableJms

Nothing works and I don't understand why..

I managed to find the answer.

One of my dependencies had a version too high.

testImplementation "org.springframework:spring-jms:6.0.3"

Once I lowered the version to 5.3.24 it all started working fine.

testImplementation "org.springframework:spring-jms:5.3.24"
