Hi Edoardo,
These kind of inconsistencies do not pose problems in most cases. For
instance I was able to get things working in Eclipse by doing a full
build on CLI and then importing the gradle eclipse plugin generated
.project and .classpath files in eclipse.
But as a counter example, the generated project files for core look for
test classes and resources from clients project under the gradle output
location. If something is modified in clients test or resources under
eclipse, the core project will not see the change unless the clients
project is re-built from CLI.
I agree this is not a big pain, but just an inconvenient setup
inconsistency.

Just my personal preference
the different output folders have not been annoying to me.
I know that the eclipse compile output is different from the output
generated running gradle on the CLI and am happy with that.

Subject: Re: Build problems in Eclipse dev environment setup
Hi Ismael,
Thanks for your response. I agree this is not a Kafka issue, its about
gradle and its eclipse plugin. I was able to resolve the compile errors
in Eclipse by manually setting the Default output folder for core
project to core/build/classes/main.
I understand Eclipse is not the popular choice for an IDE but, for me
and my other Eclipse brethren, I looked into the problems I faced and
noticed that the output folders for gradle and those for eclipse get
configured differently. The output folders in eclipse go under
<project>/bin where as in gradle they are under <project>/build. Due to
this the projects in Eclipse don't work fine unless the command line
build is completed at least once. Will it be fine if we could align
these so that inter project dependencies fall well in place in either
build? *I was looking into the possibilities of fixing that and I have a
change available that I am testing out.*
There is another discussion on the pros and cons of this here
https://discuss.gradle.org/t/eclipse-generated-files-should-be-put-in-the-same-place-as-the-gradle-generated-files/6986
People, please let me know your opinion and I will provide a PR for this
if I get this working for myself.
thanks

Hi Dhwani,
This is more about Gradle and Eclipse than Kafka and many of us use
IntelliJ IDEA so won't be able to help you. I can confirm that IntelliJ
is
able to import the project fine out of the box.

Hi,
I am trying to setup the eclipse dev environment on trunk. I have
followed
the instructions given here
https://github.com/apache/kafka/blob/trunk/README.md
https://cwiki.apache.org/confluence/display/KAFKA/Developer+
Setup#DeveloperSetup-Eclipsesetup
After I run ./gradlew eclipse in the command line followed by "Import
existing projects into workspace" in Eclipse, I am able to see the
projects. But I see the following build errors in Eclipse.
Description: The import kafka.utils.ShutdownableThread cannot be
resolved
Resource: Consumer.java
Path: /kafka-examples/src/main/java/kafka/examples
Location: line 19
Type: Java Problem
There are other errors as well but they are of a similar nature and
others
dependent on them. I can see the class ShutdownableThread in core and
core
is compiled properly. The examples project has core setup as dependency
project which seems correct. Also the command line build works just
fine.
Also I don't see any .class files generated under core/bin. They are
present under core/build/classes/main/ though. Is this due to some kind
of
mismatch between the command line build and Eclipse build?
Could you please suggest what am I missing here.
Environment:
- Eclipse Neon
- Java 1.7
- Scala 2.10.6
- CentOS 6.8
thanks
