I am running eclipse oxygen (release 4.7.3a) with maven plugin m2e (1.8.3.20180227) and java 8 (jdk1.8.0\_172)

**Updated eclipse** to Version: 2019-03 (4.11.0), m2e 1.11.0.20190220-2119, java version unchanged. 
Same behavior persists.

I have a project with a module. 
The module has `/src/main/java` and `src/test/java`
The `junit` dependency is test scope.

When I run maven install I get errors during compile

> 
> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project something: Compilation failure: Compilation failure:
> 
> 
> [ERROR] /C:/Users/me/git/base/module/src/test/java/com/company/redacted/db/IsAdminQueryTest.java:[3,24] package org.junit does not exist
>

If I change the scope of `junit` to default it compiles and runs fine.

A perhaps related symptom If I run `Maven -> Update Project`, I get an error:

> 
> Cannot nest 'module/src/main/resources' inside 'module/src/'. 
>  To enable nesting exclude 'main/' from 'module/src/'
> 
>

However `module/src` is not a java source folder.

from the maven log during the compile stage when running with `-e -X`. 

Note the **test** in the path

>

> 
> 
> [DEBUG] Stale source detected: C:\Users\ms\git\base\module\src\test\java\com\company\redacted\db\IsAdminQueryTest.java

Where should I look for the bad config?

**Update after upgrade**
I had changed the scope of junit and mockito to global to work around this problem. When I changed them back to scope: test the test case started having dependency issues/failure to compile. Clearly eclipse/maven doesn't know my test classes are test classes.

I have installed maven directly on my pc. Running mvn install from the command line has the same issues as running in eclipse.
