[Neo4j] In-Memory usage of APOC not working

No a syntax error, classpath probem:

Can't get APOC to work with in-memory usage in small example (io.github.neo4j.example01.Main from neo4j directory)

When i add the following dependency and uncomment some code (annotated with TODO in comments) in the example

<dependency>
<groupId>org.neo4j.procedure</groupId>
<artifactId>apoc</artifactId>
<version>4.2.0.1</version>
</dependency>

i am missing "apoc.path.PathExplorer" on classpath. If i use

<dependency>
    <groupId>org.neo4j.procedure</groupId>
    <artifactId>apoc</artifactId>
    <version>4.1.0.6</version>
</dependency>

i get the following exception:

Caused by: java.lang.ClassNotFoundException: org.neo4j.graphdb.TransactionGuardException

If i use older dependencies

<dependency>
    <groupId>org.neo4j.procedure</groupId>
    <artifactId>apoc</artifactId>
    <version>4.1.0.6</version>
</dependency>
<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j</artifactId>
    <version>4.1.6</version>
</dependency>
<dependency>
    <groupId>org.neo4j.driver</groupId>
    <artifactId>neo4j-java-driver</artifactId>
    <version>4.1.1</version>
</dependency>

i get the following exception while executing the example:
