如何从模块中无法访问软件包（即如何从模块中删除软件包？）

简短版本

我必须从哪个文件夹中删除什么文件才能停止错误：

可以从多个模块访问包装％s：＆lt; named＆gt;％s

：

在尝试构建Java Web网站时，我会遇到错误：我遇到了错误

可以从多个模块访问包装％s：＆lt; named＆gt;％s

例如：

package org.w3c.dom可以从一个以上的模块中访问：\＆lt ;未命名\＆gt;，java.xml
可以从多个模块访问javax.xml.parsers：\＆lt; named \＆gt;，java.xml
可以从多个模块访问netscape.javascript：\＆lt; named \＆gt;，jdk.jsobject
package org.xml.sax可以从一个以上的模块中访问：现在

> .jar 文件），或者我需要编辑配置文件以删除一行，或者我需要在计算机上的其他地方删除文件，或者我需要删除环境变量。

我不知道要删除什么文件，
我不知道要删除的.jar
我不知道要编辑什么文本文件，
我不知道要编辑什么配置文件
我don' t知道要添加，编辑或删除哪个文本文件中的哪一行

，我该如何：

制作包装％s 不是可从一个以上的模块访问

显然是Java 9和

一些您可以说您可以禁用JPMS 通过删除module-info.java
其他人坚持认为您在Java 8之后完全无法禁用JPMS，您只需要在Java 8上生活，
有些人说，如果您删除module-info，。

classpath 或modulepath

尽管我没有classpath或modulepath集：

>echo %classpath%
%classpath%

>echo %modulepath%
%modulepath%

>echo %java_home%
C:\Program Files\Java\jdk-18.0.1.1

iDE： Visual Studio代码

项目结构

Web Sine由文件和文件夹的结构组成。有些可能是按照惯例在那里的，有些可能是限制的，有些可能是额外的东西的垃圾场。不

原文

Short Version

What file do i have to delete from what folder to stop the error:

The package %s is accessible from more than one module: <unnamed>, %s

Long Version

When trying to build a Java web-site, i am getting the error:

The package %s is accessible from more than one module: <unnamed>, %s

For example:

The package org.w3c.dom is accessible from more than one module: \<unnamed\>, java.xml
The package javax.xml.parsers is accessible from more than one module: \<unnamed\>, java.xml
The package netscape.javascript is accessible from more than one module: \<unnamed\>, jdk.jsobject
The package org.xml.sax is accessible from more than one module: \<unnamed\>, java.xml

Now:

I don't know what a module is
and i don't know what a package is

But i do get get the sense that i need to delete a file (maybe a .jar file), or i need to edit a configuration file to remove a line, or i need to delete files elsewhere on my computer, or i need to delete environment variables.

i don't know what file to delete
i don't know what .jar file to delete
i don't know what text file to edit
i don't know what configuration file to edit
i don't know what line in what text file to add, edit, or remove

So, how do i:

Make package %s not accessible from more than one module

Apparently it is an bug added with Java 9 and the Java Platform Module System (JPMS), and it is not anything to do with Eclipse, NetBeans, or any IDE. It is a rule that was always there, but only Java 9 started enforcing it.

Some say you can disable the JPMS by deleting module-info.java
Others insist that you cannot disable JPMS at all after Java 8, and you just have to live on Java 8
Some have said that if you delete module-info.java it will get re-created

I don't have a module-info.java file anywhere in the folder or subfolders of the project

Others suggest it is an issue with classpath, or modulepath

Although i don't have a classpath or modulepath set:

>echo %classpath%
%classpath%

>echo %modulepath%
%modulepath%

>echo %java_home%
C:\Program Files\Java\jdk-18.0.1.1

IDE: Visual Studio Code

Project structure

The web-site is make up of a structure of files and folders. Some are probably there by convention, some are probably there by rule, and some may have been a dumping ground for extra stuff. I don't know which is which:

Research Effort

That's a restriction by the Java Platform Module System (JPMS), not by Eclipse (so don't shoot the messenger). If you delete the file module-info.java in your default package (which disables JPMS) it should work with Java 9 or higher.
