Question

我有一个（简单的）maven项目，使用org.apache.felix:maven-bundle-plugin:2.5.4打包类型为“bundle”。它产生一个正确的OSGI束罐。但是我观察到所有目标至少执行两次。我该如何防止这种情况？问题是某些目标（本例中的checkstyle）很慢，因此重复执行是一个问题。

注意：我从命令行使用maven 3.2.5。

输出或mvn clean install（删除所有不相关的信息）。请注意，许多插件执行4次。 maven-checkstyle-plugin被执行两次。

更新：这是一个已知错误（另请参阅答案K Erlandsson）：https://issues.apache.org/jira/browse/FELIX-4882

此问题现已解决（maven-bundle-plugin-2.5.5）

Answer 1

修改：由于 rmuller 已在问题中更新，因此它是一个错误：https://issues.apache.org/jira/browse/FELIX-4882。该错误已在版本expect(scope.status).toBe(200)中修复。

当我们将3.0.0升级为maven-bundle-plugin时，我记得我们遇到了类似的问题（具体来说，捆绑包已部署了两次）。我们将其降级为2.5.4以解决我们的问题。

我没有深入研究这是否是一个错误，或者2.5.3是否只有其他配置要求。

Answer 2

我尝试使用此解决方法跳过maven-bundle-plugin 2.5.4的目标部署：

<executions>
  <execution>
    <id>default-deploy</id>
    <phase>no-execute</phase>
    <goals>
      <goal>deploy</goal>
    </goals>
</execution>

这仅适用于我的情况下带限定符的版本号：例如0.3.0-RC1。使用版本号发布版本而没有限定符仍然无效：e。 G。 0.3.0。

将maven-bundle-plugin降级到2.5.3解决了这个问题，该捆绑包已经部署了两次。但我面临另一个问题： Maven Bundle Plugin fails with ArrayIndexOutOfBoundsException, "Invalid Class File" ...

根据https://issues.apache.org/jira/browse/FELIX-4556，切换为bndlib版本2.4.0对我有用。

所以我使用maven-bundle-plugin 2.5.3并使用bndlib版本2.4.0解决了我的问题：

<plugin>
  <groupId>org.apache.felix</groupId>
  <artifactId>maven-bundle-plugin</artifactId>
  <version>2.5.3</version>
  <dependencies>
    <dependency>
      <groupId>biz.aQute.bnd</groupId>
      <artifactId>bndlib</artifactId>
      <version>2.4.0</version>
    </dependency>
  </dependencies>
<plugin>

Answer 3

shouldComponentUpdate版本适合我。

当使用带有maven-bundle-plugin的“bundle”打包时，目标会被执行两次
