Question

Having an issue with a particular compiled class on Appian version 22.4.0

I am working on consolidating multiple plugins that used Appian versions 22.4.0 and 20.4.0.
My consolidated plugins is being developed on Appian version 22.4.0.

However, I am getting the following error:

NamedTypedValue.class cannot access com.appiancorp.core.expr.portable.PortableNamedTypedValue 

How would you solve such problem ?

Thanks,

-Bek

Hey, this usually happens when the compiled plugin or class was built with a java or appian SDK version that doesn’t match what appian 22.4 expects. make sure you’re compiling with the java version that appian supports, and check that the SDK you used matches the version of appian you’re running. If the plugin came from a third party, see if there’s an updated build for 22.4. also have a look at the tomcat logs for errors like “unsupported class version error” to confirm if it’s a version mismatch.

Thanks for the response.
I am using appian version 22.4 and compiling using java 8.

<dependency>
            <groupId>com.appiancorp</groupId>
            <artifactId>appian</artifactId>
            <version>22.4.0</version>
        </dependency>


I am running it locally using version 22.4 jar in .m2 repository. 

I don't see the following class: 

import com.appiancorp.core.expr.portable.PortableNamedTypedValue;


When I try to search for the missing compiled class in the jar, using java's jdk command , the class is actually missing.
Yet the class appears as one of the imports of the com.appiancorp.suiteapi.type.NamedTypedValue.class"

I hope that give you more context to my issue.

I am eager to try with an updated build for appian version 22.4.0 but how can I get it ?

Recommend, Recompile all plugins with SDK 22.4.0 and Java 8 to match your runtime environment.

Why don't you reference the sdk library (as external libraru) directly in you project and check if it works?
