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:
Could anybody help me figure out what needs to be done here?
Thank You in advance,
atlassian-scannernamespaces in your spring context files (where you have
<scan-indexes>- see the "Spring runtime integration" example below) from
atlassian-spring-scanner-processoris gone. If you had a dependency on it, remove it.
<plugins>- see example below. ** If your build then fails to find
<scope>provided</scope>- you'd been relying on those transitively.
@Scanned- this feature is removed. All classes are now scanned.
Hope developers change the text of the article for beginners https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-confluence-hello-world-macro/ , which specifies the com.atlassian.plugin library connection .spring.scanner.annotation.component.Scanned and adding the @Scanned keyword, which are no longer needed.
When your code is compiled, the compiler needs to work out what each and every identifier in your code means. As the compiler is going through the code it will find something and know what to do with it or not. Your Cannot find symbol error relates to the identifiers and means that Java cannot figure out what the "symbol" means.
The general causes for a Cannot find symbol error are things like:
