Hello,

we have our own plugin which was working earlier and stopped working after Jira software upgrade to 8.4.2 server. I get the following error message and the plugin doesn't deploy while server startup. Your help is much appreciated.

2019-11-06 00:51:10,115 localhost-startStop-1 ERROR [c.a.plugin.loaders.ScanningPluginLoader] Unable to deploy plugin 'com.example.proaction.projectinfo' from 'Unit: C:\D-Drive\asop_workspace\proaction-project-view-plugin-for-jira\project-info\target\jira\home\plugins\installed-plugins\projectinfo-1.0.8-SNAPSHOT.jar (1572981099922)'.

I run into the same issue followed by 

com.atlassian.upm.spi.PluginInstallException: Unknown error, plugin not installed
at com.atlassian.upm.core.install.AbstractPluginInstallHandler.installArtifact(AbstractPluginInstallHandler.java:122)

The cause was in  

META-INF/versions/9/module-info.class


I excluded it with following workaround

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <!--
    Workaround to exclude module-info.class from META-INF/versions/9 that is cause of
    "com.atlassian.upm.spi.PluginInstallException: Unknown error, plugin not installed"
    -->
    <configuration>
        <excludes>atlassian-plugin.xml, META-INF/MANIFEST.MF, META-INF/*.DSA, META-INF/*.SF,META-INF/versions/9/*.class</excludes>
    </configuration>
</plugin>
