扫描条目“module-info.class”时出错启动Jetty服务器时 [英] Error scanning entry "module-info.class" when starting Jetty server

问题描述

我最近在启动java服务器时看到了这个。有没有人见过这个？如果是这样的话怎么办？
我可以确认jar和module-info.class存在于相关路径中。

I'm seeing this recently when I start my java server. Has anyone else seen this? If so whats the fix? I can confirm the jar's and the module-info.class are present in the relevant paths.

推荐答案

module-info.class 是Java9（JPMS）功能。

module-info.class is a Java9 (JPMS) feature.

Jetty 9.4.9（或更新版本）支持从Java 9更改新的JAR文件。

Jetty 9.4.9 (or newer) supports the new JAR file changes from Java 9.

Issues about Java 9 features:

• https://github.com/eclipse/jetty.project/issues/1692 - 从字节码扫描中排除 module-info.class 。


• https://github.com/ eclipse / jetty.project / issues / 1797 - 正确支持 META-INF / versions / * 多版本JAR文件（JEP 238）。

• https://github.com/eclipse/jetty.project/issues/1692 - excluding module-info.class from bytecode scanning.
• https://github.com/eclipse/jetty.project/issues/1797 - supporting META-INF/versions/* Multi-Release JAR files (JEP 238) properly.
