Hi,

From my Windows machine with java version  11.0.8 installed, I ran:

mvnw clean package

with no problem.

What output do you get when you run the following? (I assume that you run the command from a Windows command terminal)

mvnw -version

Note: The mvnw command and tool is provided by graphwalker-project. It makes sure you get the correct maven version, without the need to install it yourself.

Hello:

         I still get the same error:

This is my Java version

This is the result of  [mvnw Clean Package] :

And this is result of  [ mvnw -version  ] :

I run these code on CMD.

      Regards

Hi,

Seams like the version 4.0.3 of the git-commit-id-plugin is not working with java 16.

Could you change the version from 4.0.3 to 4.0.4 in the pom.xml  and see if it makes any difference?

The pom.xml  at row 457 in the graphwalker root folder should look like: 

<plugin>
  <groupId>pl.project13.maven</groupId>
  <artifactId>git-commit-id-plugin</artifactId>
  <version>4.0.4</version>

Is this normal?

Hi,

For the command line tool specifically, have a look at https://github.com/GraphWalker/graphwalker-project/wiki/Command-Line-Tool 

You should also check out https://github.com/GraphWalker/graphwalker-project/wiki

Hello:

　　I follow the website and find that sudo does not work on CMD.So I run as administrator.But I still get the same result as before.

　    In addition, I am able to use Studio successfully.But always fails in testing,like this:

And this:

=====

I tried some solutions like：mvn clean,Check java\maven\graphwalker version.

 But it doesn't work.

Hi,

Could you provide a minimal working example project of your problems?
You can follow instructions here on how to do that.

Just seeing screenshots of the errors is not enough to determine the root cause of your issues I'm afraid.

Hi,

Thanks for the example project, it cleared things up.

Your model and you project looks fine :-)

1. When running the model:
$ java -jar graphwalker-cli-4-3-1.jar offline -g src/main/resources/com/company/SmallTest.json
{"currentElementName":"v_VerifyInitialState"}
{"currentElementName":"e_FirstAction"}
{"currentElementName":"v_VerifyFirstAction"}
{"currentElementName":"e_AnotherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeOtherAction"}
{"currentElementName":"v_NewVertex"}
{"currentElementName":"e_SomeAction"}
{"currentElementName":"v_VerifyFirstAction"}


2. Using your Runner class:
$ mvn compile exec:java -Dexec.cleanupDaemonThreads=false -Dexec.mainClass="com.company.Runner"
:

3. Using  mvn graphwalker:test

But if you want to use the graphwalker:test plugin, you need to add the @Graphwalker annotation to your

model class implementation. Grapphwalker does not use the generator and start element information

from the model json file when using the plugin.

This is what you need to add:

$ git diff

diff --git a/myProject2021/src/main/java/com/company/SomeSmallTest.java b/myProject2021/src/main/java/com/company/SomeSmallTest.java

index a0e26d7..ecb303d 100644

--- a/myProject2021/src/main/java/com/company/SomeSmallTest.java

+++ b/myProject2021/src/main/java/com/company/SomeSmallTest.java

I hoped it helped, Kristian

[hongzhi huang]

Hello:

        Thank you! It worked.

        But there still exists problem in another sample even if I tried this method , maybe it's not for the same reason.

        Could you confirm whether this problem is the problem of the sample itself or my setting is wrong.

Hi, 

I think your problem is in the pom.xml file. There are different versions of graphwalker mentioned.
Try this patch:

$ git diff pom.xml

diff --git a/TrainSignal/pom.xml b/TrainSignal/pom.xml
