无法调用 CXFInstall.getLocation() 因为 cxfInstall 为空

问题描述

我正在尝试使用最新的 Eclipse IDE (jee-2021-03) 和 apache-cxf-3.4.2 从 WSDL 文件开始生成 Web 服务客户端。

我收到此错误：

IWAB0014E Unexpected exception occurred.
  Cannot invoke "org.eclipse.jst.ws.internal.cxf.core.model.CXFInstall.getLocation()" because "cxfInstall" is null
      java.lang.NullPointerException: Cannot invoke "org.eclipse.jst.ws.internal.cxf.core.model.CXFInstall.getLocation()" because "cxfInstall" is null

我在 macOS Big Sur 11.3（使用 Apple Silicon M1）上使用 AdoptOpenJDK 8。 Apache CXF 刚刚下载并存储在本地文件夹中。 在 Eclipse 首选项中，在 Web 服务/CXF 2.x 首选项下，我可以正确地看到我的 CXF 运行时。 它不依赖于 WSDL 本身，因为我也无法使用任何其他 WSDL 运行 Web 客户端生成。

相同的 WSDL 已成功用于使用旧版 MacBook Pro 和 macOS Big Sur 11.2.1、Eclipse jee-2020-06、apache-cxf-3.3.7 和 Java SE 8 (1.8.0_181) 生成客户端。

我在 Google 上没有找到任何关于它的信息...

有人遇到过同样的问题吗？
