我正在开发一个 Eclipse 4 RCP 项目，其中包含一个插件包和一个用于单元测试的包片段。目标平台是使用 Eclipse 目标定义(.target 文件)来定义的。 Maven 与 Tycho 用于在 Eclipse 之外构建项目( list 优先，使用定义目标平台的 .target 文件)。
现在我想将 Mockito 包含在目标平台中进行模拟。 Eclipse Orbit 提供了 org.mockito (1.9.5) bundle 。它取决于 org.hamcrest(也可以在 Orbit p2 站点上找到)，因此我也将其添加到目标定义中。当我从目标文件设置 Eclipse 的目标平台时，目标平台状态 View 中将显示以下内容:
尽管 org.hamcrest.library 和 org.hamcrest.core 都存在(两个包都导出 org.hamcrest 1.3.0 包)，org.mockito 包声称缺少 org.hamcrest 包。
尽管如此，我还是将 org.mockito 和 org.hamcrest.library 添加到了 MANIFEST.MF 中测试插件片段的依赖项中。
Require-Bundle: org.junit;bundle-version="4.11.0",
org.hamcrest.library;bundle-version="1.3.0",
org.mockito;bundle-version="1.9.5"
该片段似乎可以编译，但测试无法运行。 tycho-surefire-plugin 报告:
An error has occurred. See the log file [...]\target\work\configuration\1405514016520.log.

从 Eclipse PDE 启动插件测试实际上会产生相同的与 mockito 相关的错误(缺少 SWT 相关的错误，但存在其他包解析错误，因为我通常不从 Eclipse 运行这些测试，并且没有消除一些冲突)来自启动配置的 bundle )。
即使该包肯定是由另一个所需的包从目标平台导出的，但丢失导入包错误的可能原因是什么？如何修复此设置？
最佳答案
我最近在 Tycho 构建和从 PDE 启动运行时 Eclipse 时遇到了同样的问题:
!ENTRY org.mockito 4 0 2018-03-14 11:53:00.671
!MESSAGE FrameworkEvent ERROR
!STACK 0
org.osgi.framework.BundleException: Could not resolve module: org.mockito [6]
Unresolved requirement: Import-Package: COM.jrockit.reflect; resolution:="optional"
Unresolved requirement: Import-Package: jrockit.vm; resolution:="optional"
Unresolved requirement: Import-Package: org.apache.tools.ant; resolution:="optional"
Unresolved requirement: Import-Package: org.apache.tools.ant.types; resolution:="optional"
Unresolved requirement: Import-Package: org.hamcrest; version="[1.0.0,2.0.0)"
我能够在这两种情况下解决这个问题，而无需重新打包 Mockito。
- 在 PDE 中，将
org.hamcrest显式添加到目标平台，而不仅仅是org.hamcrest.core:
对应的.target代码:
<location includeAllPlatforms="false" includeConfigurePhase="true" includeMode="planner" includeSource="true" type="InstallableUnit">
<unit id="org.hamcrest" version="1.1.0.v20090501071000"/>
<unit id="org.mockito" version="1.9.5.v201605172210"/>
<repository location="http://download.eclipse.org/tools/orbit/downloads/drops/R20180206163158/repository/"/>
</location>
在第谷中做同样的事情:
<plugin> <groupId>org.eclipse.tycho</groupId> <artifactId>target-platform-configuration</artifactId> <version>${tycho-version}</version> <configuration> <dependency-resolution> <extraRequirements> <!-- Workaround for an issue with mockito depending on hamcrest --> <requirement> <type>eclipse-plugin</type> <id>org.hamcrest</id> <versionRange>0.0.0</versionRange> </requirement> </extraRequirements> </dependency-resolution> </configuration> </plugin>
关于eclipse - 即使 Hamcrest 是依赖项，Mockito bundle 也找不到 org.hamcrest 包，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24781833/
