java - 当使用带有 maven-bundle-plugin 目标的“bundle”打包时，会执行两次

Question

我有一个（简单）maven 项目，其包装类型为“bundle”，使用org.apache.felix:maven-bundle-plugin:2.5.4. 它会生成一个正确的 OSGI 包 jar。但是我观察到所有目标都至少执行了两次。我该如何防止这种情况？问题是一些目标（本例中的 checkstyle）很慢，所以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，许多插件执行了 4 次。maven-checkstyle-plugin被执行两次。

更新：这是一个已知错误（另见答案 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

编辑：由于rmuller在问题中已更新，这是一个错误：https ://issues.apache.org/jira/browse/FELIX-4882 。该错误已在版本中修复3.0.0。

我记得当我们升级maven-bundle-plugin到2.5.4. 我们将其降级2.5.3以解决我们的问题。

我还没有深入研究这是否是一个错误，或者是否有其他配置要求2.5.4。

Answer 2

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

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

在我的情况下，这仅适用于带有限定符的版本号：例如0.3.0-RC1. 带有没有限定符的发布号的发布版本仍然无法正常工作：例如0.3.0.

将 maven-bundle-plugin 降级到 2.5.3 解决了这个问题，即捆绑部署了两次。但是我遇到了另一个问题： Maven Bundle Plugin fails with ArrayIndexOutOfBoundsException, "Invalid Class File"...

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

所以我通过使用maven-bundle-plugin 2.5.3和使用bndlib版本解决了我的问题2.4.0：

<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

该版本maven-bundle-plugin-2.5.5适用于我。
