It would be nice if the author of the patches would update the bug tracker and
not someone else of the current staff.

** [bugs:#868] IntelliJ Modules are not shared correctly**
**Status:** open-fixed
**Group:** OTHER
**Labels:** Intellij
**Created:** Mon Sep 05, 2016 02:02 PM UTC by Bernd Sahre
**Last Updated:** Mon Oct 17, 2016 05:18 PM UTC
**Owner:** Bernd Sahre
**Description**:
Host Alice has a Module which contains a test folder, sources folder, and a
<modulename>.iml file. There are two classes in the src folder.
If the Host shares this Module in Intellij with Bob, Bob gets all the files
(.java and .iml) but not the whole Module.
Problem 1: The folders containing the files are only shown as directories,
independent of their host-side status (e.g. Module, src folder, test folder,
etc.). As a result, Bob cannot create classes (as it's only possible in Java
Module src folders, not in plain directories).
Problem 2: Empty folders are not transmitted.
**Problem-Analysis**:
Comparing the two projects of Alice and Bob, the result is following:
In the _.idea_ folder (which contains the project meta data), there are
differences in
* _misc.xml_
* _workspace.xml_
* _modules.xml_
All other files are equivalent (except for own system configurations).
In the _modules.xml_ file all Modules of the project are listed, and the
transmitted Modul does not appear there. After copying the _module.xml_ file
from the Host to the client the corresponding module is shown correctly.
Another Problem (not solved with the Approach to Solution) is that nested
Modules (Modules in Modules) are not transmitted correctly, because its hard to
compute the path to the inner .iml file.
**Approach to solution**
Intellij provides a _ModuleManager_ through the OpenAPI, which has a method
"loadModule" to load a Module from an .iml file and add it to the project. This
solves the problem.
To call this method, it is recommend to register a new class in the
SarosLifeCycleListener and the Picocontainer so the method is called every time
when Ressources are shared.
It is also appropiate to embed this method with
~~~java
ApplicationManager.getApplication().invokeLater(new Runnable() {
@Override
public void run() {
ApplicationManager.getApplication().runWriteAction(new Runnable() {
loadModule(filepath);
....
~~~
to secure thread safety.
