You are expected to use a new Eclipse build for the development. Also, developers who have the JDT JUnit runtime bundles (.runtime, 4.runtime) checked out and pull the latest changes will run into the above issue.

The documentation also notes: We do not support running tests in a setup where an old Eclipse build (not having JUnit 5 support) is using a new Eclipse build (having JUnit 5 support) as target. The developer should either change the test runner to JUnit 5 or delete them so that new launch configurations are created with JUnit 5 test runner while running the tests.

You can provide tags to be included in or excluded from a test run in the Configure Tags dialog of JUnit launch configuration.Ĭonsult the documentation for the complete list of features.Įclipse documentation states that if a developer is running JUnit 5 tests via in Eclipse without JUnit 5 support, that means developer has JUnit 4 as the test runner in launch configurations.

JUnit Jupiter's Assertions, Assumptions, DynamicContainer and DynamicTest classes are now added to Eclipse Favorites by default.

Java search now includes a 'Module' search scope.Īccording to Eclipse Oxygen.1a documentation, JUnit 5 support includes However, Java runtime 9 must be in build path to compile a modular project.Īn existing non-modular project can be converted to a modular project by creating a module-info.java for the project.Ī library or a container can be added to the module path instead of classpath. The Eclipse documentation states that it is not mandatory to run Eclipse with a Java 9 runtime to get the Java 9 support.

The IDE has added features to support Java Modules including compiler updates and search features.

The Eclipse compiler for Java implements all the new Java 9 language enhancements. With this release, STS has been updated to Eclipse Oxygen.1a, which includes support for JDK 9 and JUnit 5 out of the box. Pivotal recently released version 3.9.1 of its Spring Tool Suite (STS), the Eclipse-based IDE for developing applications in Spring Framework.
