Have you put the dependency below in your project's pom.xml?
```xml
<dependency>
<groupId>net.bytebuddy</groupId>
<artifactId>byte-buddy</artifactId>
<version>1.7.11</version>
</dependency>
```
version can be another you want.

Resolved by replace the drool version to 7.24.0.t043 as it is resolved the issue for compatibility with dev tool( spring boot)
I'd like to work with Redis for manipulating sessions.But I get failure when running the spring boot app.So I guess that this error is coming from maven dependencies especially version conflicts.
Here is my maven dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

</dependency>
<dependency>
<groupId>io.lettuce</groupId>
<artifactId>lettuce-core</artifactId>
<version>5.0.0.RELEASE</version>
</dependency>
</dependencies>
Notice that I added two dependencies in above pom.xml which there artifactId are spring-session-data-redis and lettuce-core.These dependencies are respectively responsible for Redis connection and ensuring thread safety for session connections.
When I run the spring boot app, I get the belowed error:
APPLICATION FAILED TO START
Description:
An attempt was made to call the method org.springframework.data.redis.connection.RedisConnection.getConfig(Ljava/lang/String;)Ljava/util/List; but it does not exist. Its class, org.springframework.data.redis.connection.RedisConnection, is available from the following locations:
jar:file:/C:/Users/aoutir/.m2/repository/org/springframework/data/spring-data-redis/2.0.10.RELEASE/spring-data-redis-2.0.10.RELEASE.jar!/org/springframework/data/redis/connection/RedisConnection.class
It was loaded from the following location:
file:/C:/Users/aoutir/.m2/repository/org/springframework/data/spring-data-redis/2.0.10.RELEASE/spring-data-redis-2.0.10.RELEASE.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.data.redis.connection.RedisConnection
Please any help is very appreciated,thanks in advance for your reply.
I have spent a whole day to resolve the exactly same issue. And after a whole day R&D, I found the solution.
dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-data-rest')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('org.springframework.boot:spring-boot-starter-security')
implementation('org.springframework.boot:spring-boot-starter-data-redis')
implementation('org.springframework.session:spring-session-data-redis')
runtimeOnly('org.springframework.boot:spring-boot-devtools')
testImplementation('org.springframework.boot:spring-boot-starter-test')
runtimeOnly('org.flywaydb:flyway-core')
runtimeOnly('com.h2database:h2')
// runtimeOnly('mysql:mysql-connector-java')
}
Use 'spring-boot-starter-data-redis' and 'spring-session-data-redis'.
Remove lettuse dependency as it is included in spring-boot-starter-data-redis as dependency.
Here is your dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>

<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>
Simply delete the explicit version for spring-session-data-redis and go with the version from the spring boot parent pom.
If you want to change the version of spring-session-data-redis, you have to ensure that none of the transitive dependencies is managed by the parent pom. If I downgrade to version 1.3 (version 1.7 could not be found) I end up with the following version mismatch as revealed by mvn -X dependency:tree:
[ESC[1;36mDEBUGESC[m] org.springframework.session:spring-session-data-redis:jar:1.3.3.RELEASE:compile
[ESC[1;36mDEBUGESC[m] org.apache.commons:commons-pool2:jar:2.5.0:compile (version managed from 2.4.2)
[ESC[1;36mDEBUGESC[m] org.springframework.data:spring-data-redis:jar:2.0.10.RELEASE:compile (version managed from 1.7.10.RELEASE)
Please replace the dependency
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
with
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
The version management is done automatically and the started will initialize the redis cache.
I tried creating a Spring Project from Spring Initializr for the first time in my local computer. But I am getting these errors #GetMapping cannot be resolved to a type.

Can someone help me with this? Is there some dependency I am missing?
You have all dependenices which required for spring boot to run and I used your same pom and its worked, few points:
If you have
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
then not required:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
you can delete these dependencies as starter includes it.
Also add maven plugin
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
and after this from command line: run mvn clean install
3. then try to rebuild project
4. if still do not work then move your starter-web as first dependency and again check.
Under file -> Invalidate caches->check(Clear file system cache and Local History, Cleared downloaded shared indexes)
enter image description here
I recommend you to start with https://start.spring.io/ for Spring Initalizr project. You're missing this dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
I use a H2 database for my Spring Application. The thing is, everything works. I can access, store and reconnect to the database. However, I get the warning by my IDE
Cannot resolve class or Package H2
at this
spring.datasource.driver-class-name=org.h2.Driver
It's a bit confusing since I don't know if and how I have to deal with that. Here was once a similar question but the answer does not help and I don't know if I am allowed to ask this question again or if I should post my question in the existing thread?
Here is my application.properties
spring.datasource.url=jdbc:h2:file:~/afile;DB_CLOSE_ON_EXIT=FALSE;AUTO_RECONNECT=TRUE
spring.datasource.username=no:)
spring.datasource.password=no:)

I've seen this before -- and I'm fairly certain it's because your database driver has the <scope>runtime</scope> in your POM. This means that at compile time the driver isn't in the classpath, and I guess the property file inspection is using the compile time classpath.
If you remove the scope from your dependency, the inspection error should go away.
At the moment I'm taking a look into Spring Boot 2, OAuth2 and single sign on. I'm running a sample project but am getting:
ClassNotFoundException: org.springframework.security.oauth2.client.web.OAuth2LoginAuthenticationFilter
I'm unable to located the Maven dependency that will give me this class.
I've tried every combination of spring-security core, starter etc.

Any help would be greatly appreciated in nailing down the correct dependencies.
I filed a bug report with Spring for this issue. While it's an ongoing conversation, I did resolve the missing dependency. Just include:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-oauth2-client</artifactId>
<version>5.0.3.RELEASE</version>
</dependency>
