无法打包插件

如何解决无法打包插件

我创建了一个 Eclipse 插件，其中包含以下清单文件：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Commitlinking
Bundle-SymbolicName: com.polarion.commitlinking;singleton:=true
Bundle-Version: 1.0.0.202101092309
Bundle-Classpath: com.polarion.commitlinking_1.0.0.202101092309.jar
Bundle-Activator: com.polarion.commitlinking.Activator
Bundle-vendor: POLARION
Require-Bundle: javax.inject,org.eclipse.osgi,org.eclipse.jface,org.eclipse.e4.ui.model.workbench,org.eclipse.e4.ui.di,org.eclipse.e4.ui.services,org.eclipse.e4.core.di.annotations,org.eclipse.core.runtime,org.eclipse.e4.core.di,org.eclipse.e4.core.contexts;bundle-version="1.8.400",org.eclipse.e4.ui.workbench,org.eclipse.core.commands,org.eclipse.ui.workbench,org.eclipse.ui,com.polarion.alm.ws.client
Bundle-requiredExecutionEnvironment: JavaSE-15
Bundle-ActivationPolicy: lazy
Import-Package: javax.annotation;version="1.2.0",javax.inject;version="1.0.0",org.eclipse.core.expressions,org.eclipse.core.runtime;version="3.5.0",org.eclipse.e4.core.commands,org.eclipse.e4.core.di.extensions;version="0.16.0",org.eclipse.e4.core.services.events,org.eclipse.e4.ui.dialogs,org.eclipse.e4.ui.workbench.modeling,org.eclipse.jface.text,org.eclipse.ui.commands,org.eclipse.ui.menus,org.eclipse.ui.plugin,org.osgi.service.event;version="1.4.0"
Automatic-Module-Name: com.polarion.commitlinking

不幸的是，将相关的 jars 包括为外部 jars 并不允许我成功创建插件，所以我尝试改为（按照 vogella 上的建议）导出目标平台并创建一个父 pom 并在其中放置我的插件项目和另一个使用目标平台管理依赖项的项目：父pom：

目标平台项目：

插件pom如下：

         .....

但是，当我运行 mvn clean package 时，出现以下异常：

Internal error: org.eclipse.tycho.repository.local.MirroringArtifactProvider$MirroringFailedException: Could not mirror artifact osgi.bundle,org.apache.log4j,1.2.17.2019-11-22 into the local Maven repository.See log output for details. /opt/polarion/polarion/plugins/org.apache.log4j_1.2.17.2019-11-22 (Is a directory)

这是因为其中一个依赖项，即 org.apache.log4j_1.2.17.2019-11-22 实际上是一个 ddirectory，里面有一个 log4j-lib 插件。这在 IDE 中运行项目时工作正常，但我不知道如何正确解决这个问题。任何帮助将不胜感激！

解决方法

所以实际的解决方案是使用现有的 jar 档案选项创建一个新插件。将该插件添加为我的插件的依赖项，并将其添加到模块部分的 parent pom.xml。需要对依赖项进行一些修补，但将生成的 jar 文件添加到 dropins 文件夹似乎现在已经起作用了。
