(This is the corrected follow-up to https://issues.apache.org/jira/browse/SPARK-2903) Right now, `mvn compile test-compile` fails to compile Spark. (Don't worry; `mvn package` works, so this is not major.) The issue stems from test code in some modules depending on test code in other modules. That is perfectly fine and supported by Maven. It takes extra work to get this to work with scalatest, and this has been attempted: https://github.com/apache/spark/blob/master/sql/catalyst/pom.xml#L86 This formulation is not quite enough, since the SQL Core module's tests fail to compile for lack of finding test classes in SQL Catalyst, and likewise for most Streaming integration modules depending on core Streaming test code. Example: ``` [error] /Users/srowen/Documents/spark/sql/core/src/test/scala/org/apache/spark/sql/QueryTest.scala:23: not found: type PlanTest [error] class QueryTest extends PlanTest { [error] ^ [error] /Users/srowen/Documents/spark/sql/core/src/test/scala/org/apache/spark/sql/CachedTableSuite.scala:28: package org.apache.spark.sql.test is not a value [error] test("SPARK-1669: cacheTable should be idempotent") { [error] ^ ... ``` The issue I believe is that generation of a `test-jar` is bound here to the `compile` phase, but the test classes are not being compiled in this phase. It should bind to the `test-compile` phase. It works when executing `mvn package` or `mvn install` since test-jar artifacts are actually generated available through normal Maven mechanisms as each module is built. They are then found normally, regardless of scalatest configuration. It would be nice for a simple `mvn compile test-compile` to work since the test code is perfectly compilable given the Maven declarations. On the plus side, this change is low-risk as it only affects tests. yhuai made the original scalatest change and has glanced at this and thinks it makes sense. Author: Sean Owen <srowen@gmail.com> Closes #1879 from srowen/SPARK-2955 and squashes the following commits: ad8242f [Sean Owen] Generate test-jar on test-compile for modules whose tests are needed by others' tests

This plugin forces the generation of jar containing streaming test classes,
|
|
so that the tests classes of external modules can use them. The two execution profiles
|
|
are necessary - first one for 'mvn package', second one for 'mvn test-compile'. Ideally,
|
|
'mvn compile' should not compile test classes and therefore should not need this.
|
|
However, an open Maven bug (http://jira.codehaus.org/browse/MNG-3559)
|
|
causes the compilation to fail if streaming test-jar is not generated. Hence, the
|
|
second execution profile for 'mvn test-compile'.
