Jetty（9.4.12）：上下文上下文oejwWebAppContext @ 2af004b webapp /的启动失败，不可用

Question

我正在使用码头（9.4.12）在macOS（Java 11）上提供Web应用程序。

尽管码头已经启动，但该服务仍然不可用。我和往常一样使用了相同的War文件，但是唯一的区别是，我已经将Java从版本10更新到了版本11。这个问题是否有可能的修复？

错误

Answer 1

Java 11字节码的扫描在4天前（2018年11月1日）刚刚合并。

https://github.com/eclipse/jetty.project/issues/2941

Eclipse Jetty项目正在等待Asm 7.0 final的发布（于2018年10月27日发布），以便可以正确扫描Java 11字节码。

即将发布的Jetty 9.4.13版本应包含此修复程序。

同时，您可以：

• 使用快速入门在生成时生成扫描结果，完全跳过了运行时字节码扫描步骤。一些用户报告说，这对他们来说效果很好（甚至缩短了启动时间）。
• 或从https://oss.sonatype.org/content/repositories/jetty-snapshots/使用Jetty 9.4.13-SNAPSHOT （直到完成9.4.13最终发行）
• 针对Java 8构建类（直到最终的9.4.13版本可用）
