Java17 - appengine:run - Does not add JAVA_USER_OPTS to run command

@ludoch Do you have any advice on this? Thanks!

[howesda]

Is there any movement on this - the deadline for moving off Java 8 on AppEngine is approaching?

Would I be better just going to Java 11, or does this same problem happen there too?

[ludoch]

Sorry, I lost track of this one.

I was able to configure the local devappserver flags with changing this in the pom.xml:

              <plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>appengine-maven-plugin</artifactId>
                <version>2.5.0</version>
                <configuration>
                    <jvmFlags>
                        <item>--add-opens</item>
                        <item>java.base/java.time.format=ALL-UNNAMED</item>
                    </jvmFlags>                   
                </configuration>
            </plugin>

Full documentation is under https://cloud.google.com/appengine/docs/legacy/standard/java/maven-reference#appenginerun

Thanks @ludoch

I'll try this later. Should this also be the solution for appengine:deploy too?

[ludoch]

No, the ref doc is for appengine:run target.
For prod deployment, what you are doing is correct (i.e appengine-web.xml env variable)
Sorry, it is not well unified. Env setup on local machines is quite different than in prod.

[howesda]

I look forward to trying this - thanks for such a quick and exhaustive response

This works for me locally, so please feel free to close this issue.
