java - Unresolved Portlet 部署要求

Question

由于奇怪的 Unresolved 依赖关系问题，Java Portlet 部署到 Liferay 7.2 失败

我想使用 Maven 在 Java 8_u202 上构建一个基于 LR 7.2(提供了 CE Bunlde 和 TC9.0.17)的 Portlet。

当我将 portlet WAR 复制到 liferay/deploy 时，我在 tomcat 日志中得到了巨大的堆栈跟踪:

除了最后一个依赖项之外的所有依赖项都是“分辨率=可选”(这使得它们无关？)。

我怀疑“(&(osgi.ee=JavaSE)(version=9)”是这里的问题。对 Java 9 的引用从哪里来？我的 POM 没有提到 Java9，而且我没有它安装在我的系统上。

感谢您的帮助... 问候， 克劳斯

Answer 1

可选包确实不应该成为问题。然而Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=9))"是。它基本上告诉解析器一个包需要 Java 9(或更高版本)运行时。

很难说这个要求到底是如何融入到你的 bundle 中的。你说你部署了一个WAR文件，这意味着它被 WAB Generator 转换为 bundle ( WAB ) 。我不太确定它到底考虑了什么，但这是 可能是什么原因造成的:

• WAR不知何故确实是用 Java 9 编译的
• WEB-INF/liferay-plugin-package.properties文件在 WAR包含添加此要求的明确说明(复制/粘贴问题？)
• WAR 中的其他内容(依赖项？)文件使 WAB Generator添加要求

可能的解决方法是添加 -noee=true WEB-INF/liferay-plugin-package.properties中的说明。我自己从未这样做过，但如果文档正确，则应将其传递给 Bnd并且该要求不应添加到 bundle 中。当然，如果确实存在Java版本不匹配，这只会导致其他错误。
