maven - 带有 OpenJDK 11.0.2 和 BouncyCastleProvider 的 Maven

问题描述

  1. Maven 正确构建

    # mvn archetype:generate -DgroupId=com.help.idea -DartifactId=client -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false

    # mvn install:install-file -Dfile=rs2xml.jar -DgroupId=net.proteanit.sql -DartifactId=rs2xml -Dversion=1.0 -Dpackaging=jar

    # mvn 包

  2. 但是在运行jar时会出现以下错误

    java -jar target/client-1.0-SNAPSHOT.jar

Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider
    at com.help.idea.authen.ClientMain.main(ClientMain.java:76)
Caused by: java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider
    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582)
    at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)
    at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)

我有以下 pom.xml

尝试了谷歌的许多建议，但无法正确解决。提前致谢。

解决方案

欢迎来到 StackOverflow。错误消息告诉您您的班级ClientMain无法访问该班级BouncyCastleProvider。造成这种情况的一个可能原因是您启动的 Java 虚拟机 (JVM) 看不到包含该类的 JAR。此类 JAR 必须与选项--class-path一起提及。

查看您的启动命令，您可以看到没有指定类路径。解决此问题的一种方法是使用选项枚举所有直接和传递依赖--class-path项（尽管这是很多工作）。

另一方面，这个项目可能创建了一个所谓的fat JAR，其中包含所有依赖项。那个，你可以用这么短的命令启动。查看target文件夹，看看是否有另一个 JAR 可用于启动。可能名称中带有某些东西-jar-with-dependencies（不要以他们的名义sources或javadoc以他们的名义发布任何东西，那是没有意义的）。

如果这不能解决您的问题，请关注Darren 的评论并向我们展示完整的 pom，以便我们查看整个上下文。
