tycho - JUnit4Provider 不工作

Question

我正在尝试让打包类型为 eclipse-test-plugin 的项目工作(我有一个雄心勃勃的目标，就是有一天让它执行测试，但现在只有两个类里面有空的测试方法)。

我假设问题只存在于我们使用目标配置文件，所以需要的插件(或其他)不会自动加载。在没有最新的文档或示例的情况下，我猜测这种用例的 pom.xml 应该看起来像这样:

<dependencies>
    <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-junit4</artifactId>
        <version>${see.below}</version>
    </dependency>
</dependencies>

<build>
    <sourceDirectory>src</sourceDirectory>
    <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-surefire-plugin</artifactId>
            <version>0.22.0</version>
            <configuration>
                <providerHint>junit4</providerHint>
            </configuration>
        </plugin>
    </plugins>
</build>

(因为没有依赖项，我得到了一个 ClassNotFoundException: org.apache.maven.surefire.junit4.JUnit4Provider，这就是类所在的位置。)

现在如果我使用 2.18.1 或以下版本的 surefire-junit4，我会收到以下错误:

An error has occurred. See the log file C:\workspaces\workspace\org.acme.project.rxp-build\org.acme.project.rxp.it\target\work\data\.metadata\.log.
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.22.0:test (default-test) on project org.acme.project.rxp.it: An unexpected error occured while launching the test runtime (return code 13). See log for details. -> [Help 1]

Aaand 有问题的日志文件包含:

如果我使用 surefire-junit4 的 2.19 版本，我会收到以下消息:

我有点怀疑 surefire-api 和 surefire-junit4 有相同的版本，所以我确保 Maven 为两者加载相同的版本，但是有行为没有变化。

这里有什么问题？如何获取要构建的测试插件？

Answer 1

好的，如果目标平台文件包含，它可以在没有愚蠢的 Maven 依赖项的情况下工作

<unit id="org.hamcrest.core" version="0.0.0"/>
<unit id="org.junit" version="0.0.0"/>
<unit id="org.eclipse.jdt.junit.runtime" version="0.0.0"/>
<unit id="org.eclipse.jdt.junit4.runtime" version="0.0.0"/>

Manifest.MF 包含

Require-Bundle: org.eclipse.jdt.junit4.runtime,
 org.junit
