Hi,

I've took 4.5-RC1 for a spin, but unfortunately something seems to be amiss.

Configuration:

Eclipse Platform 4.6.1.v20160907-1200 (Neon 1)

Scala IDE for Eclipse 4.5.0.rc1-2_11-201611221557-2c71a49

Maven Integration for Scala IDE 0.5.1.201410131304c

I've checked out sources of Apache Spark 2.0.2 and used scala-m2e to import it. Result: gazzilion compilation errors.

I was able to minimize it down to this: 

import just two modules that are self contained: common/tags and common/network-common

observe compilation errors in src/test/java: org.apache.spark.network.TestUtils is not found, despite the source file being right there. I've also examined output directory and .class file is found in the expected location. Quick inspection with javap confirms that the class was compiled fine.

Just to make sure, with the following configuration Spark 2.0.2 compiles just fine (I had to generate some sources by running mvn directly and tweak a few build path entries)

Eclipse Platform 4.5.2.v20160212-1500 (Mars 2)

Scala IDE for Eclipse 4.4.1.v-2_11-201605041057-92a3ed3

If I could help with diagnosing this issue further please let me know!

Hello Rafal,

before rebuilding projects in existing workspace please remove all .cache- files (in root of project). They are making problems and unexpected errors because Zinc uses slightly different format (first of all new Zinc zips analysis files)

Hope this is the problem

Hi Wiesław,

unfortunately no. I created a fresh workspace and scrubbed git working copy with git clean -fdx. I verified that all the .cache-* files were gone. After importing the modules mentioned above into workspace, exactly same errors appeared.

cheers,
Rafał

No issues so far with nightly based upgrade, thanks ;-)

[wpopie...@virtuslab.com]

Could you please, send me some minimal project with this error? Would be very helpful

[Rafał Krzewski]

As I said above, I'm getting this error in https://github.com/apache/spark

It's sufficient to "Import existing Maven projects" for common/tags and common/network-common modules using scala-m2e

Can you do that, or would you prefer me to rip these out and zip up a sample workspace?

Cheers,

Rafał

[Rafał Krzewski]

Hi,

I've prepared a minimal workspace with en extracted bit of Apache Spark that exhibits a single compilation error. Complete workspace compressed with bzip2 is 8.4MB. https://caltha.eu/~rafal/scala-ide/spark-repro.tar.bz2

cheers,

Rafał

this is ok for me. Starting digging... thanks

Hi Rafal,

there a bug in on our side (I mean Scala IDE) in integration with Zinc compiler. This is new functionality so can suffer of childish ailment. It does not look serious in fixing so I can make a solemn vow that will be removed in RC2 in the beginning of next week :).

W.

[Rafał Krzewski]

Excellent! I'll be happy to test RC2 once it's out :)

Thanks,

Rafał

[Rafał Krzewski]

For the record, I've tried the nightly build with https://github.com/scala-ide/scala-ide/pull/1131 merged in and I confirm that the problems with importing Apache Spark observed  with RC1 are now fixed.

Thanks,

Rafał
