atlas-run: Unable to scan for host components in plugin clases

[Dani]

I've searched through all available topics in the Atlassian community and couldn't find a resolution.

The error message is:

Could anyone help in identifying what is the cause of this?

Hi Dani,

Which java source level are you using to compile your plugin? I'm asking you that because a very similar problem was observed when we were switching from Java 1.7. to 1.8

• PLUG-1098 - The plugin system fails to load plugins compiled with a java 8 source level

thanks

Hey @Gabriel Ribeiro

I couldn't find any Java version specified in the pom file, could it be the problem?

[Gabriel Ribeiro]

Hi Dani,

Usually, if don't specify the Java version, Maven will use the default JDK option, you can check what's the default version running mvn -version in the terminal.

To specify which JDK version you want Maven to use to compile your project, you can set the -source and -target options in the compiler or, you can add the following parameters to the POM file:

<project>

  [...]

  <properties>

  <maven.compiler.source>1.8</maven.compiler.source>

  <maven.compiler.target>1.8</maven.compiler.target>

  </properties>

  [...]

</project>

You will find more details in the Apache Maven Plugin documentation. 

thanks

So I have been using JDK 1.8 to compile, But Bamboo says that for that specific version they support 1.8 JDK version.
