当类只包含 JUnit4 注释时，使 Eclipse 默认为 JUnit4 而不是 JUnit5

Question

A recent upgrade of groovy which brought with it JUnit5 has resulting in Eclipse wanting to run every test under JUnit5. I can sort of work around this by going to run configurations and tell Eclipse to use JUnit4, however this gets tedious.

Is it possible to tell Eclipse to always use JUnit4 for a particular project, including new tests?

Answer 1

在启动配置中，您应该能够根据需要选择JUnit 3、4或5。

Answer 2

You can specify a profile and activate it in Eclipse only.

Example (assuming your problem arose by having a dependency to groovy-all ):

    <profiles>
        <profile>
            <id>eclipse-groovy-no-junit5</id>
            <dependencyManagement>
                <dependencies>
                    <dependency>
                        <groupId>${groovy.groupId}</groupId>
                        <artifactId>groovy-all</artifactId>
                        <version>${groovy.version}</version>
                        <type>pom</type>
                        <exclusions>
                            <exclusion>
                                <groupId>${groovy.groupId}</groupId>
                                <artifactId>groovy-test-junit5</artifactId>
                            </exclusion>
                        </exclusions>
                    </dependency>
                </dependencies>
            </dependencyManagement>
        </profile>
    </profiles>

Then go to

Project -> Properties -> Maven -> Active Maven Profiles

and specify the profile name eclipse-groovy-no-junit5 .

Remark: groovy.groupId is set to org.codehaus.groovy (it's a variable, because it will be replaced by org.apache.groovy in 4.x) and groovy.version is set to 3.0.8 .

If you want to be a bit more verbose, you can add...

    <activation>
        <activeByDefault>false</activeByDefault>
    </activation>

...but it's the default anyway.
