Cannot define class using reflection

[weisern]

Simply cloning the DataflowTemplates repo (yesterday's commit id: df38854) in GCP cloudshell, and
running a single GCP Cloud Build yaml step with maven goal of 'test':

steps:
- name: 'gcr.io/cloud-builders/mvn'
  id: 'Build, Test, ...'
  args:
  - 'clean'
  - 'test'
  - '--batch-mode'

...results in unit test errors.

Example:
org.apache.beam.vendor.guava.v26_0_jre.com.google.common.util.concurrent.UncheckedExecutionException: java.lang.UnsupportedOperationException: Cannot define class using reflection: Cannot define nest member class java.lang.reflect.AccessibleObject$Cache + within different package then class org.apache.beam.vendor.bytebuddy.v1_9_3.net.bytebuddy.mirror.AccessibleObject
Caused by: java.lang.UnsupportedOperationException: Cannot define class using reflection: Cannot define nest member class java.lang.reflect.AccessibleObject$Cache + within different package then class org.apache.beam.vendor.bytebuddy.v1_9_3.net.bytebuddy.mirror.AccessibleObject

The Cloud Build, Dataflow, and Compute service accounts have already been granted appropriate roles. All necessary APIs are enabled.

It is using pom.xml from commit id: df38854 where :
<beam.version>2.18.0</beam.version>
<java.version>1.8</java.version>

Adding the below dependency for artifactId, beam-vendor-bytebuddy-1_9_3, to pom.xml still produces same errors:
https://mvnrepository.com/artifact/org.apache.beam/beam-vendor-bytebuddy-1_9_3/0.1

<!-- https://mvnrepository.com/artifact/org.apache.beam/beam-vendor-bytebuddy-1_9_3 -->
<dependency>
    <groupId>org.apache.beam</groupId>
    <artifactId>beam-vendor-bytebuddy-1_9_3</artifactId>
    <version>0.1</version>
</dependency>

Help please?

Using latest commit id 7cd79f4 which does not have duplicate com.google.truth dependency

<dependency>
      <groupId>com.google.truth</groupId>
      <artifactId>truth</artifactId>
      <version>${truth.version}</version>
      <scope>test</scope>
</dependency>

Still gives 79/236 unit test failures as attached:
