Alexander Reshetov commented on CALCITE-994:
--------------------------------------------
Didn't investigate the root of issues with Checkstyle yet.
But I suppose Java Build Path issue caused by this:
Top-level pom.xml requires Java 1.7 (through maven-compiler-plugin).
Also some modules requires even earlier version:
- calcite-mongodb - 1.5
- calcite-plus - 1.5
- calcite-spark - 1.5
- calcite-ubenchmark - 1.6
So the question is that specific versions really needed or it just hasn't been
updated for a while?
If they needed - then this JDK versions should be presented on development
machine.
If not - pom.xml files should be updated to use current JDK 1.8
----
And here is quick and dirty workaround. Use it only if you really need to start
working right now.
Two actions used below:
- Set correct JRE Library
In project/module properties go to Java Build Path - Libraries
Edit JRE System Library and set it to JavaSE-1.8
Apply
- Disable Checkstyle
In project/module properties go to Checkstyle - Main
Uncheck "Checkstyle active for this project"
OK
After project import open module (Eclipse's project) properties for each module
(listed below) apply next actions
- Set correct JRE Library
- Disable Checkstyle
to modules/projects:
- calcite-avatica
- calcite-avatica-server
- calcite-core
- calcite-example-csv
- calcite-example-function
- calcite-linq4j
- calcite-mongodb
- calcite-piglet
- calcite-plus
- calcite-spark
- calcite-splunk
- calcite-ubenchmark
