maven compile failure. cannot access

i am acessing a class, which is part of the Elasticsearch server. When i compile the code inside Eclipse, i have no problems. doing it in Maven i get an error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project flume-ng-elasticsearch-sink: Compilation failure
[ERROR] \Eclipse\Workspace\flume\flume-ng-sinks\flume-ng-elasticsearch-sink\src\main\java\org\apache\flume\sink\elasticsearch\client\ElasticSearchTransportClient.java:[202,19] error: cannot access Level

My code is:

Settings.Builder settingsBuilder = Settings.builder()
    .put("cluster.name", clusterName);

The property "Level" is defined in a class from the Elasticsearch Project. Code is available here.

Any idea, which might be wrong?

thanks,

Helmut

Compiler and Java version

In my case the problem was a combination of two things.

First, the Java version of the dependency (the class that "cannot access") was way ahead of that of the project I am building now (17 versus 11), so the compiler would not understand it.

Second, the compiler version in the project I am building was too old, so it would not complain correctly about the class file version. I upgraded the compiler plugin (from 2.2 to 3.10.1) and then it would complain about a class file too advanced for the Java version I was using.

After those two corrections, I moved forward to later errors.

Found the problem.
In pom file of the project the dependency to Log4J had a scope of "test", so it was not available to the compile scope. Removed the scope test and all is fine now.
