Eclipse Ivyde托管库未导出到可运行的jar文件中

到目前为止

，Eclipse将Ivyde托管库导出到可运行的JAR文件中，但我不确定为什么它最近停止工作。

怎么了？如何解决这个问题？

ivy.xml

<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation= "http://ant.apache.org/ivy/schemas/ivy.xsd">
  <info organisation="com.example" module="eclipse-ivyde-export-issue" />
  <dependencies>
    <dependency org="org.json" name="json" rev="20220320"/>
  </dependencies>
</ivy-module>

复制问题的步骤

clone

  git克隆 [emagy＆nbsp; emagy＆nbsp; -ivyde-export-issue.git

将克隆的项目导入eclipse workspace。
/p>
右键单击类src/com..example/main.java在项目树和选择运行为→Java应用程序。请参阅输出：{“ key”：“ value”}。
右键单击项目并选择导出→Java→可运行的JAR文件。
选择类的启动配置com.example.main和库处理：[x]提取物需要库中生成的jar。点击完成。

尝试运行生成的JAR文件：

  $ java -jar eclipse-ivyde-export-issue.jar
线程“ main” java.lang.noclassdeffounderror中的例外：org/json/jsonobject
  在com.example.main.main（main.java:8）
引起：java.lang.classnotfoundexception：org.json.jsonobject
  at Java.base/jdk.internal.loader.builtinclassloader.loadclass（buildinclassloader.java:641）
  at Java.base/jdk.internal.loader.classloaders $ appclassloader.loadclass（classloaders.java:188）
  at Java.base/java.lang.classloader.loadclass（classloader.java:520）
  ...另外

环境

Eclipse 2022-06 m2（
m2
4.24.0
尝试运行生成的

） -06使用OpenJDK 8工作正常，

我用Eclipse 2020-06和OpenJDK 8测试了同一项目。JAR Export发出警告“此操作重新包装引用的库”，IVYDE托管类都包含在生成的JAR文件中。

（这个问题也发布到 eclipse社区论坛。

原文

The problem

So far, Eclipse has exported IvyDE managed libraries into a runnable JAR file, but I'm not sure why it has stopped working recently.

What's wrong? How can I fix the issue?

ivy.xml

<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation= "http://ant.apache.org/ivy/schemas/ivy.xsd">
  <info organisation="com.example" module="eclipse-ivyde-export-issue" />
  <dependencies>
    <dependency org="org.json" name="json" rev="20220320"/>
  </dependencies>
</ivy-module>

Steps for reproducing the issue

Clone the project:

git clone [email protected]:haba713/eclipse-ivyde-export-issue.git

Import the cloned project into Eclipse workspace.
Right-click the class src/com.example/Main.java in the project tree and
choose Run as → Java Application. See the output: {"key":"value"}.
Right-click the project and choose Export → Java → Runnable JAR file.
Choose the launch configuration for the class com.example.Main and
Library handling: [x] Extract required libraries into generated JAR. Click
Finish.

Try to run the generated JAR file:

$ java -jar eclipse-ivyde-export-issue.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONObject
  at com.example.Main.main(Main.java:8)
Caused by: java.lang.ClassNotFoundException: org.json.JSONObject
  at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641)
  at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188)
  at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520)
  ... 1 more

Environment

Eclipse 2022-06 M2 (4.24.0 M2)
IvyDE 2.2.0.final-201311091524-RELEASE
OpenJDK 17.0.3+7-Debian-1deb11u1
Debian GNU/Linux 11 (Bullseye)

Eclipse 2020-06 with OpenJDK 8 works fine

I tested the same project with Eclipse 2020-06 and OpenJDK 8. JAR export gives a warning "This operation repacks referenced libraries" and IvyDE managed classes are included into the generated JAR file.

(The question was posted also to Eclipse Community Forums.)
