我想在我的Eclipse插件中使用logback.slf4j，所以我把它作为要求添加到我的清单中。MF 文件：
Require-Bundle: org.eclipse.equinox.app,
org.eclipse.equinox.launcher,
...,
ch.qos.logback.slf4j;bundle-version="1.0.7"
然后我使用额外的调试（mvn clean package -X）开始构建，在输出中我可以看到logback.slf4j及其依赖项已正确下载：

[INFO] Resolving class path of MavenProject: com.example.myplugin:com.example.myplugin:0.0.1 @ ~Desktoptycho_examplebundlescom.example.myplugin.polyglot.build.properties
然后 Tycho 打印已解析的捆绑包列表，这也确认新下载的插件已正确解析：

...
但是，最终我得到以下结果：

Missing Constraint: Require-Bundle: ch.qos.logback.slf4j; bundle-version="1.0.7"

有没有人看到类似的问题？
如 https://stackoverflow.com/a/45190630/301049 中所述
我设法在pom.xml使用以下target-platform-configuration插件配置明确添加了对测试插件片段的依赖：
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<configuration>
<dependency-resolution>
<extraRequirements>
<requirement>
<type>eclipse-plugin</type>
<id>org.acme.module.fragment</id>
<versionRange>0.0.0</versionRange>
</requirement>
</extraRequirements>
</dependency-resolution>
</configuration>
</plugin>
