Known Problems in Configuration
IntelliJ IDEA has a known problem with importing sources of other module as resources.
Which is the case with the Flow project where flow-client
has flow-server
sources as a resource.
The fix for this is to during development time comment out the flow-server
resource for the flow-client/pom.xml
.
<resource><directory>../flow-server/src/main/java</directory></resource>
Note
|
Build flow-client package
To build the flow-client package remember to un-comment the resource.
