Question

java.lang.NoClassDefFoundError: Failed to link net/glxn/qrgen/javase/QRCode

当我在 .pom 文件中添加此代码时，出现上述错误

<build>
  <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>2.4.3</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <artifactSet>
                                <includes>
                                    <include>net.glxn.qrgen:javase</include>
                                    <include>org.json:json</include>
                                </includes>
                            </artifactSet>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
    </build>

我必须添加 maven-shade-plugin 以添加对第 3 方插件的支持。

有什么想法为什么我会收到此错误吗？

更新pom.xml

Answer 1

尝试添加依赖项:

https://mvnrepository.com/artifact/net.glxn/qrgen/1.4

<!-- https://mvnrepository.com/artifact/net.glxn/qrgen -->
<dependency>
    <groupId>net.glxn</groupId>
    <artifactId>qrgen</artifactId>
    <version>1.4</version>
</dependency>
