IntelliJ在类路径上包含来自另一个Maven模块的测试类

Question

I have a problem accessing resource file, when I run tests in IntelliJ. When I run the same tests from maven everything works as expected.

The maven3 project has 2 modules: database-module and webapp-module. webapp-module depends on database-module.

Files:

database-module/src/main/resources/dataSource.xml
database-module/src/test/resources/dataSource.xml
database-module/src/test/java/org/example/DataSourceTest.java
webapp-module/src/test/java/org/example/HomeControllerTest.java

There is a test class DataSourceTest in database-module. The test uses dataSource.xml from classpath.

DataSourceTest.java contains:

@Value("classpath:dataSource.xml")
private Resource myDataSource;

The annotation @Value is org.springframework.beans.factory.annotation.Value.

When I run the test, the variable myDataSource contains the data from src/test/resources. It works well for maven and for IntelliJ.

I have another test HomeControllerTest in webapp-module. The test also uses dataSource.xml in the same way as DataSourceTest. However there is a difference in running the test from maven and from IntelliJ:

If I run HomeControllerTest from maven, it works as expected: it uses database-module/src/main/resources/dataSource.xml. If I run HomeControllerTest from IntelliJ, it uses database-module/src/test/resources/dataSource.xml.

The file dataSource.xml is present only in database-module, there is no dataSource.xml in webapp-module.

I printed out the classpath in IntelliJ while running HomeControllerTest and I was surprized that test-classes from database-module is present, even though HomeControllerTest is part of webapp-module.

The classpath (when the test is run from IntelliJ):

C:/myproject/database-module/test-classes
C:/myproject/database-module/classes
C:/myproject/webapp-module/test-classes
C:/myproject/webapp-module/classes

The tests use JUnit4.

Why is there database-module/test-classes on classpath when I invoke the test from webapp-module? How can I change IntelliJ behaviour to match the maven way of constructing classpath?

The problem turned out to be an issue with IntelliJ version 13. I tested the described problem and my test works when I run only one particular test. However when I try to run all the test ("Test kind": "All in package" and "Search for tests": "In whole project") I get into the trouble described in the question.

According to JetBrains JIRA the issue is fixed in IntelliJ version 14 - I didn't check.
