Error while running java unit tests: java.lang.NoClassDefFoundError: com/uber/m3/tally/Scope

idelmas · October 10, 2022, 5:08pm

I am trying to run the unit test from the hello world application but get the following error when running them:

java.lang.NoClassDefFoundError: com/uber/m3/tally/Scope

I tried explicitly adding the dependency to my pom.xml tree with no success.

Here is the line that causes the error:

    @Rule
    public TestWorkflowRule testWorkflowRule =
            TestWorkflowRule.newBuilder()
                    .setWorkflowTypes(HelloWorldWorkflowImpl.class)
                    .setDoNotStart(true)
                    .build();

here are the dependencies form my pom.xml

    <dependencies>

Do you get same error when not using release candidate sdk version but last official v1.16.0?

You should not have to explicitly add

<dependency>
    <groupId>com.uber.m3</groupId>
    <artifactId>tally-m3</artifactId>
    <version>0.2.0</version>
</dependency>

Try removing it as well.

<dependency>
    <groupId>io.temporal</groupId>
    <artifactId>temporal-testing</artifactId>
    <version>1.16.0</version>
</dependency>

add

<scope>test</scope>

please and try again

idelmas · October 10, 2022, 6:36pm

still the same problem

tihomir · October 10, 2022, 6:41pm

Weird, can you share your entire pom please?
You should only need

<dependency>
    <groupId>io.temporal</groupId>
    <artifactId>temporal-sdk</artifactId>
    <version>${version.temporal}</version>
</dependency>

<dependency>
    <groupId>io.temporal</groupId>
    <artifactId>temporal-testing</artifactId>
    <scope>test</scope>
    <version>${version.temporal}</version>
</dependency>

temporal-sdk pulls in tally:

io.temporal:temporal-sdk:jar:1.16.0:compile
|  +- io.temporal:temporal-serviceclient:jar:1.16.0:compile
|  |  +- com.uber.m3:tally-core:jar:0.11.1:compile

Thanks for info, took your pom, removed depends for service-client (not needed) so it looks like:

And ran

mvn dependency:tree > depends.txt
vi depends.txt

I can see com.uber.m3:tally-core:jar:0.11.1:compile

Thanks to you dependency tree I found my problem, hoping this might help someone else in the future.

I had to install the temporal sdk, serviceclient, testing dependencies manually into maven but did not install them specifying the pom. Once I did that the dependencies showed up and the code now works.

For anyone coming along, download the jar AND the pom, then run the following from the same directory:

mvn install:install-file -Dfile=temporal-sdk-1.16.0.jar -DgroupId=io.temporal -DartifactId=temporal-sdk -Dversion=1.16.0 -Dpackaging=jar -DpomFile=temporal-sdk-1.16.0.pom
mvn install:install-file -Dfile=temporal-testing-1.16.0.jar -DgroupId=io.temporal -DartifactId=temporal-testing -Dversion=1.16.0 -Dpackaging=jar -DpomFile=temporal-testing-1.16.0.pom
mvn install:install-file -Dfile=temporal-serviceclient-1.16.0.jar -DgroupId=io.temporal -DartifactId=temporal-serviceclient -Dversion=1.16.0 -Dpackaging=jar -DpomFile=temporal-serviceclient-1.16.0.pom

Thank you for you help @tihomir
