Getting error "cannot find symbol: class Scanned" while upgrading plugin from 7.2.1 to 8.2.2 Edited

[Karan_Sehgal]

I am getting following error while trying to upgrade my custom plugin from 7.2.1 to 8.2.2:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.6.1:compile (default-compile) on project perforce-changelist-plugin: Compilation failure
[ERROR] /C:/Apps/perforce-changelist-plugin/src/main/java/com/nvidia/plugins/jira/perforcechangelist/adminui/AdminServlet.java:[29,64] cannot find symbol
[ERROR] symbol: class Scanned
[ERROR] location: package com.atlassian.plugin.spring.scanner.annotation.component

I see some packages were changed from 7.2.1 to 8.2.2. I modified those dependencies. However I don't see any spring plugins released for 8.2.2 https://mvnrepository.com/artifact/com.atlassian.jira/jira-bundled-plugins?repo=springio-plugins-release 

and I am unable to find the following dependencies in 8.2.2:

<dependency>
<groupId>com.atlassian.plugin</groupId>
<artifactId>atlassian-spring-scanner-annotation</artifactId>
<version>${atlassian.spring.scanner.version}</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.atlassian.plugin</groupId>
<artifactId>atlassian-spring-scanner-runtime</artifactId>
<version>${atlassian.spring.scanner.version}</version>
<scope>runtime</scope>
</dependency>

<plugin>
<groupId>com.atlassian.plugin</groupId>
<artifactId>atlassian-spring-scanner-maven-plugin</artifactId>
<version>${atlassian.spring.scanner.version}</version>
<executions>
<execution>
<goals>
<goal>atlassian-spring-scanner</goal>
</goals>
<phase>process-classes</phase>
</execution>
</executions>
<configuration>
<scannedDependencies>
<dependency>
<groupId>com.atlassian.plugin</groupId>
<artifactId>atlassian-spring-scanner-external-jar</artifactId>
</dependency>
</scannedDependencies>
<verbose>false</verbose>
</configuration>
</plugin>

Could anybody help me figure out what needs to be done here?

Thank You in advance,

Changes required if you're upgrading from atlassian-spring-scanner 1.x to 2.0+

• VERY IMPORTANT! Change all the atlassian-scanner namespaces in your spring context files (where you have <scan-indexes> - see the "Spring runtime integration" example below) from http://www.atlassian.com/schema/atlassian-scanner to http://www.atlassian.com/schema/atlassian-scanner/2. 
• Remove your dependency on atlassian-spring-scanner-runtime.
• Change your dependency on atlassian-spring-scanner-annotation to be <scope>provided</scope>.
• atlassian-spring-scanner-processor is gone. If you had a dependency on it, remove it.
• Add atlassian-spring-scanner-maven-plugin to <plugins> - see example below. ** If your build then fails to find org.springframework.stereotype or javax.inject, add spring-context or javax.inject to <dependencies> with <scope>provided</scope> - you'd been relying on those transitively.
• Remove use of @Scanned - this feature is removed. All classes are now scanned.
• Remove 'auto-imports' attribute from <scan-indexes>.
