HelloWorld plugin - the origin server did not find a current representation for the target resource

[Класс точности]

Hello

I installed JDK, Atlassian SDK on windows machine, and created plugin by running "atlas-create-confluence-plugin"

After that i run "atlas-run" command, it started local web server with link

http://localhost:1990/confluence

But when i try to open it in browser, i get 404 error with following text:

HTTP Status 404 – Not Found

---

Type Status Report

Message Not found

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

---

Apache Tomcat/9.0.11

Any ideas, what i did wrong?

Here is log from \target\container\tomcat9x\cargo-confluence-home\logs 

127.0.0.1 - - [09/Nov/2020:13:54:10 +0300] "GET /cargocpc/index.html HTTP/1.1" 200 124

There is 5 directories in webapps,

cargocpc
confluence
host-manager
manager
synchrony-proxy

if i move index.html from cargocpc to any directory, webserver can reach it.

Excepts "confluence".

Debugging the issue, its observed that its a JAVA version issue. The current version of Java on my machine is 1.8 , whereas Confluence needs

Java 11 or Java 17

Refer - Supported Platforms | Confluence Data Center and Server 8.7 | Atlassian Documentation

So to resolve the issue below changes are needed in the pom.xml file

<confluence.version>8.5.0</confluence.version>
<confluence.data.version>8.5.0</confluence.data.version>
<amps.version>8.10.1</amps.version>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>

 Updating Java from 1.8 to 11 using the below steps did the trick

Steps to update Java on M1 Mac 

1. Set Java 11 as the Default Version (if needed):

   brew link --overwrite --force openjdk@11

2. Update the .bash_profile & .zshrc  

vi ~/.bash_profile 
vi ~/.zshrc  

export PATH=/opt/homebrew/bin:/Users/actio/Library/Python/3.9/bin:/usr/bin/:$HOME/.cargo/bin:$PATH
export JAVA_HOME=/opt/homebrew/opt/openjdk@11
export PATH=$PATH:$JAVA_HOME/bin

Observe the JAVA_HOME changed to point to JDK 11

Verify the Installation:

Once installed, open a new Terminal window and type java -version to check if Java 11 is the default version now. The output should show version 11.

Re-run mvn -v:

Open a new Terminal window and run mvn -v again to verify that Maven is now using Java 11. The Java version in the Maven output should reflect Java 11.

@Класс точностиdid you find any solution for the problem?

Interested as well, I am trying to develop a plugin but continue to get this error.

[James Watts]

As information, using this post https://stackoverflow.com/questions/63290222/atlassian-confluence-sdk-problem-starting-app-404

Basically set the <confluence.version> and <confluence.data.version> to something higher than version 7.0 in the pom.xml file.

I got past the 404, but now just get a blank page.  But some progress.

[James Watts]

I decided to start fresh:

1. atlas-create-confluence-plugin
2. Update pom.xml and updated below:
   1. <confluence.version>7.20.1</confluence.version>
   2. <confluence.data.version>7.20.1</confluence.data.version>
3. atlas-run

http://localhost:1990/confluence now results in a login screen.

Hope this helps you get past your issue.

@James Watts ,

Facing the blank screen issue after updating the confluence version. Do you know how to get past the blank screen issue ?

Cheers
