使用maven tycho构建一个由maven-dependency-plugin下载的清单条目Bundle-ClassPath

Question

我有一个带有此清单的eclipse插件:

...
Bundle-ClassPath: .,
 lib/drools-api.jar,
 lib/drools-core.jar,
...

现在我们不想放入drools-api.jar和drools-core.jar控制源代码,因此我们使用插件从maven存储库中获取它们:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
      <execution>
        <id>copy-bundle-classpath-libs</id>
        <phase>validate</phase>
        <goals>
          <goal>copy</goal>
        </goals>
        <configuration>
          <outputDirectory>lib</outputDirectory>
          <overWriteReleases>true</overWriteReleases>
          <overWriteSnapshots>true</overWriteSnapshots>
          <overWriteIfNewer>true</overWriteIfNewer>
          <stripVersion>true</stripVersion>
          <artifactItems>
            <artifactItem>
              <groupId>org.drools</groupId>
              <artifactId>drools-api</artifactId>
            </artifactItem>
            <artifactItem>
              <groupId>org.drools</groupId>
              <artifactId>drools-core</artifactId>
            </artifactItem>
            ...

但是,我们第一次构建此模块时,它会失败,因为这会发生:

[WARNING] Missing classpath entry lib/drools-api.jar ...
[WARNING] Missing classpath entry lib/drools-core.jar ...
...
[INFO] --- maven-dependency-plugin:2.1:copy (copy-bundle-classpath-libs) ... ---
...
[INFO] Copying drools-api-5.2.0-SNAPSHOT.jar to .../lib/drools-api.jar
[INFO] Copying drools-core-5.2.0-SNAPSHOT.jar to .../lib/drools-core.jar
...
[INFO] --- maven-osgi-compiler-plugin:0.10.0:compile (default-compile) ... ---
...
[INFO] Compiling 458 source files to ...
// ERROR because drools-api is not in the compilation classpath

如果我们再次构建它,它会成功,因为在lib构建开始之前jar已经在目录中:没有警告,并且jar在编译类路径中.

我们如何解决这个问题,以便我们不需要在源代码管理中提交jar并仍然使用Bundle-ClassPath？

注意:插件的当前实现要求我们使用Bundle-ClassPath:使用Require-Bundle而不是选项.

这是一个已知的错误。
