Method Summary

Methods
Modifier and Type	Method and Description
`RepositorySystemSession`	`getRepositorySession()` Gets the currently active repository session.
`MavenSession`	`getSession()` Gets the currently active session.
`void`	`setSession(MavenSession session)` Sets the currently active session.

- Method Detail
  - setSession
```
void setSession(MavenSession session)
```
    Sets the currently active session. Some legacy components are basically stateful and their API is missing parameters that would be required to delegate to a stateless component. Saving the session (in a thread-local variable) is our best effort to record any state that is required to enable proper delegation.
    
    Parameters:
    session - The currently active session, may be null.
  - getSession
```
MavenSession getSession()
```
    Gets the currently active session.
    
    Returns:
    The currently active session or null if none.
  - getRepositorySession
```
RepositorySystemSession getRepositorySession()
```
    Gets the currently active repository session.
    
    Returns:
    The currently active repository session or null if none.
