Unable to use custom scalars upgrade from 1.18.9 to 1.18.10 (Or 2.0RC1)

[dpalmmna]

While attempting to upgrade from 1.18.9 to 1.18.10 the generation now fails on custom scalars.

The code that causes errors is

public String getPackageName(String classFullNameParam)

The method exists with message Could not find the package for the class 'org.locationtech.jts.geom.Geometry', due to: org.locationtech.jts.geom.Geometry.

The pom.xml configuration is :

How to allow the generation with this new code, using types from external libraries?

[etienne-sf]

Hello,

I'm surprised and annoyed that, with all the integration tests I have, this bug is possible.

I could repeat this issue with the pom you provided. And yes, the dependencies for each custom scalar is mandatory. A workaround is to add the dependency to the plugin, like this:

            <plugin>
                <groupId>com.graphql-java-generator</groupId>
                <artifactId>graphql-maven-plugin</artifactId>

                <executions>
                    <execution>
                        <goals>
                            <goal>generateClientCode</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <packageName>fr.cs.maps.mission.mus.database</packageName>
                    <customScalars>
                        <customScalar>
                            <graphQLTypeName>timestamp</graphQLTypeName>
                            <javaType>java.time.LocalDateTime</javaType>

I didn't check all the scalars you've defined, so perhaps other dependencies must be added for your all project to work.

It will be solved in a next version. Etienne

[dpalmmna]

Adding the dependency worked. Thxs. This is an acceptable solution.

Hello,

The correction for this issue has been released the 2.3 version. I'll see to add it into the 1.x version
