JDK 11.0.2-无法在ECLIPSE中派生模块描述符 [英] JDK 11.0.2 - Unable to derive module descriptor in ECLIPSE
问题描述
我正在尝试运行其他人制作的项目.我将项目添加到eclipse中，它会自动生成一个module-info.java，并且由于模块是基于名称的，因此我会收到警告，所以我假设这可能是我的问题.我对模块不熟悉，并且很难理解在线上的一些资源.这是我的运行时错误.
I'm trying to run a project someone else made. I added the project to eclipse and it automatically generated a module-info.java and I'm getting warnings because the modules are name based, so I'm assuming this may be my issue. I am not familiar with Modules and I'm having a hard time understanding some of the resources online. Heres my runtime error.
Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for C:\Users\under\Desktop\RSPS\Emerald\Server\lib\xpp3.jar
Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class org.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer not in module
这是我的module-info.java
Here is my module-info.java

我的jar文件(重命名为xpp3，因为stackoverflow上的资源表示文件名的语法可能是一个问题)包含错误指出不是模块的文件，
My jar file (renamed to xpp3 because a resource on stackoverflow said the syntax of the file name could be an issue) contains the files that the error says isn't a module,
org.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer
所以我的问题是如何使用eclipse将它们添加到模块中?
So my question is how do I add these to the module using eclipse?
另外，关于stackoverflow的另一篇文章说要确保配置了构建路径，以使我的库位于模块路径而不是类路径中，我也确保这样做. https://prnt.sc/owu9r3
Also, another post on stackoverflow said to make sure the build path was configured so that my libs were in my modulepath not my classpath, I made sure to do this as well. https://prnt.sc/owu9r3
我已经尝试解决了几个小时，非常感谢您的帮助.
I've been trying to figure this out for hours now, any help is greatly appreciated.
推荐答案
似乎 JAR文件包含提供者配置文件 META-INF/services/org.xmlpull.v1.XmlPullParserFactory ，其内容如下:
The JAR file contains the provider-configuration file META-INF/services/org.xmlpull.v1.XmlPullParserFactory with the following content:
org.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer
这两个提供程序类被指定为逗号分隔的列表，而不是每行一个类.请参见 ServiceLoader的Javadoc (以粗体显示)由我):
The two provider classes are specified as comma-separated list instead of one class per line. See Javadoc of ServiceLoader (highlighting in bold by me):
该文件包含混凝土的全限定二进制名称列表提供商类，每行一个.
另请参见错误消息:它表示提供商类，而不是提供商类，并且后没有空格，，因此它仅使用无效名称命名单个类. org.xmlpull.mxp1.MXParser，org.xmlpull.mxp1_serializer.MXSerializer
See also the error message: it says Provider class and not Provider classes and there is no space after the , so it names only the single class with the invalid name org.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer.
关于模块描述符的误导性错误消息表示 module-info.java 文件指定的https://openjdk.java.net/projects/jigsaw/quick-start#services"rel =" nofollow noreferrer> JPMS服务(自Java 9起可用).这可能会导致在Java 9及更高版本中发生的错误在Java 8及更低版本中未发生，或者在较早的时间点(在启动应用程序时而不是在使用应用程序时)发生了错误.
The misleading error message talking about a module descriptor implies that the implementation of services specified via META-INF/services/* files (available since Java 6), has been merged with the new implementation of JPMS services specified via the module-info.java file (which are available since Java 9). This might result that in Java 9 and higher errors occur that did not occur in Java 8 and lower or that an error occurs at an earlier point in time (already when starting the application instead of when using it).
