blueprint-maven-plugin JDK 兼容性答案

【问题标题】：blueprint-maven-plugin JDK compatibilityblueprint-maven-plugin JDK 兼容性
【发布时间】：2021-08-30 13:23:59
【问题描述】：

我们有一个正在运行（在 Karaf 中）并使用 JDK 8 构建的微服务项目。
现在我正在尝试使用 JDK 11（实际上是 OpenJDK）构建它，但我收到了这个错误。

这是否意味着这个插件与 JDK 11 不兼容？

还是有别的意思？

在插件的官方页面上，如果插件与 JDK 11 兼容，我看不到任何信息。插件最新版本似乎是 1.10.0，这是我正在尝试使用的版本（但那是最后一次构建在 2018 年，所以它被其他东西取代了吗？）。

【解决方案1】：

在将 karaf 部署的项目从 jdk8 迁移到 jdk11 时，我刚刚遇到了几个与 blueprint-maven-plugin 类似的问题。由于 blueprint-maven-plugin 自 2018 年 5 月以来仍处于 1.10.0 版本，因此在这些问题中进行了讨论

我有一个解决方法，将 org.apache.xbean:xbean-finder-shaded 的版本覆盖为 blueprint-maven-plugin 的最新版本：

<pluginManagement>
    <plugins>
        ...
        <plugin>
            <groupId>org.apache.aries.blueprint</groupId>
            <artifactId>blueprint-maven-plugin</artifactId>
            <version>1.10.0</version>
            <dependencies>
                <dependency>
                    <groupId>org.apache.xbean</groupId>
                    <artifactId>xbean-finder-shaded</artifactId>
                    <version>4.20</version>
                </dependency>
            </dependencies>
        </plugin>

谢谢，我可能会尽快尝试。
