问题描述

com.azure:azure-identity jar包版本从1.2.0 升级到1.12.2 版本之后报错，错误信息如下：

错误分析

应用日志显示存在依赖管理错误导致的method not found 报错。

• The following method did not exist:    com.microsoft.aad.msal4j.ConfidentialClientApplicationBuilder.logPii(Z)Lcom/microsoft/aad/msal4j/AbstractApplicationBaseBuilder;
• The called method's class hierarchy was loaded from the following locations:    com.microsoft.aad.msal4j.ConfidentialClientApplication.Builder: file:/C:/java/soft/gradle-7.4.2-bin/gradle-7.4.2/caches/modules-2/files-2.1/com.microsoft.azure/msal4j/1.11.0/38df9693f67ea1f01f35ebbe9411f0760c9ac77f/msal4j-1.11.0.jar

需要调整class path以确保能读取到正确的依赖包。

Correct the classpath of your application so that it contains compatible versions of the classes com.azure.identity.implementation.IdentityClientBase and com.microsoft.aad.msal4j.ConfidentialClientApplication$Builder

综合以上，错误的原因是项目依赖中可能存在了多个版本的msal4j。当前解析出的msal4j-1.11.0.jar与升级后的azure-identity-1.12.2不兼容。
