Using atlassian sdk with newer confluence versions

Hi community,

I need to develop against a specific recent version of confluence (server/DC), i.e. the new 8.3 release, because we are running into problem with that version, only.

I tried to bump the confluence version in our POM to 8.3.0, however it seems the atlassian SDK toolchain cannot deal with it:

 /D:/jasmine/Documents/yFiles/Graphity/yworks-diagrams-for-confluence/src/main/java/com/yworks/plugins/confluence/helper/[3,28] cannot access com.atlassian.bonnie.Searchable
  bad class file: C:\Users\moeller\.m2\repository\com\atlassian\confluence\confluence-bonnie\8.3.0\confluence-bonnie-8.3.0.jar(com/atlassian/bonnie/Searchable.class)
    class file has wrong version 55.0, should be 52.0

because not surprisingly the time for Java 8 is finally over. Unfortunately I also cannot use Java 11, setting the maven.compiler versions to 11 yields:

 Fatal error compiling: invalid target release: 11

again, not surprisingly since the bundled maven is from prehistoric times.

I should add that I’m NOT a maven pro. Has anyone managed to develop against recent confluence versions and can share their knowledge? That would be awesome.

Hi @JasmineMller

in the pom/xml file, keep the following parameters at 1.8


Make sure you have Java version 11 installed on your system and check if the SDK correctly detects it with the atlas-version command

ATLAS Version:    8.2.7

ATLAS Scripts:    /Applications/Atlassian/atlassian-plugin-sdk/bin

AMPS Version:     8.1.2

Default locale: en_PL, platform encoding: UTF-8
OS name: "mac os x", version: "13.3.1", arch: "aarch64", family: "mac"

In addition, make sure that the artifactId is in the correct version, for me it is 8.2.0


I hope this will help you compile your app correctly
