Modules not found when trying to inject module-info.java
问题
我有一个使用Apache的PDFBox的JavaFX项目。我想使用JLink来构建它的JRE，但是由于PDFBox是一个自动模块，所以我不能这样做。因此，我正在尝试在其中注入一个module-info文件。
我使用jdeps生成了这个module-info文件：
module org.apache.pdfbox {
requires org.bouncycastle.pkix;
requires org.bouncycastle.provider;
requires transitive commons.logging;
requires transitive java.desktop;
requires transitive java.xml;
requires transitive org.apache.fontbox;
exports org.apache.pdfbox.contentstream;
// ... 其他exports ...
}
在jar文件夹中，我运行了：
javac --patch-module org.apache.pdfbox=pdfbox-2.0.20.jar module-info.java
但是我得到了以下错误：
pdfbox/module-info.java:2: 错误: 找不到模块: org.bouncycastle.pkix
requires org.bouncycastle.pkix;
^
pdfbox/module-info.java:3: 错误: 找不到模块: org.bouncycastle.provider
requires org.bouncycastle.provider;
^
pdfbox/module-info.java:5: 错误: 找不到模块: commons.logging
requires transitive commons.logging;
^
pdfbox/module-info.java:8: 错误: 找不到模块: org.apache.fontbox
requires transitive org.apache.fontbox;
^
4 个错误
我该如何解决这个问题？还有更好的解决方法吗？提前谢谢。

I have a JavaFX project that uses Apache's PDFBox. I want to use JLink to build a JRE of it, but I can't since PDFBox is an automodule. Thus, I'm trying to inject a module-info file in it.
I generated this module-info file using jdeps:
module org.apache.pdfbox {
requires org.bouncycastle.pkix;
requires org.bouncycastle.provider;
requires transitive commons.logging;
requires transitive java.desktop;
requires transitive java.xml;
requires transitive org.apache.fontbox;
exports org.apache.pdfbox.contentstream;

exports org.apache.pdfbox.pdfwriter;
exports org.apache.pdfbox.pdmodel;
exports org.apache.pdfbox.pdmodel.common;

exports org.apache.pdfbox.rendering;
exports org.apache.pdfbox.text;
exports org.apache.pdfbox.util;
exports org.apache.pdfbox.util.filetypedetector;
}
At the jar's folder, I ran:
javac --patch-module org.apache.pdfbox=pdfbox-2.0.20.jar module-info.java
But then I got
pdfbox/module-info.java:2: error: module not found: org.bouncycastle.pkix
requires org.bouncycastle.pkix;
^
pdfbox/module-info.java:3: error: module not found: org.bouncycastle.provider
requires org.bouncycastle.provider;

pdfbox/module-info.java:5: error: module not found: commons.logging
requires transitive commons.logging;
^
pdfbox/module-info.java:8: error: module not found: org.apache.fontbox
requires transitive org.apache.fontbox;
^
4 errors
How can I fix this? Is there any better workaround? Thanks in advance.

因为自动模块的问题，您不能直接使用 jlink。但是您可以按照这个教程 https://github.com/dlemmermann/JPackageScriptFX 进行操作，该教程也使用了 jlink，但仅用于创建一个专用运行时，而无需将项目模块化。我在我的项目中也在使用 PDFBox，所以我知道它是可行的。免责声明：由于我是上述教程的共同作者，所以我持有偏见 
英文:
You cannot use jlink directly because of the automatic module issue. But you can follow this tutorial https://github.com/dlemmermann/JPackageScriptFX which also uses jlink but only to create a dedicated runtime without having to modularize your project. I am also using PDFBox in my project, so I know it works. Disclaimer: I am biased because I am the co-author of the above mentioned tutorial

我找到了一个关于逐步制作 module-info.class 的教程。
对我而言，这个教程有效，成功为 org.apache.commons.math3 创建了 module-info.class。
<https://www.youtube.com/watch?v=bO6f3U4i0A0&t=293>
对我来说，“模块未找到”问题没有出现。
英文:
I found a tutorial about making the module-info.class step by step.
It worked for me to create module-info.class for org.apache.commons.math3 .
<https://www.youtube.com/watch?v=bO6f3U4i0A0&t=293>
For me, the 'module not found' issue didn't show up.
