使用Azure管理库的Maven项目出现未知编译错误求助

我正在尝试在Maven项目中使用Microsoft Azure管理库管理访问令牌，通过com.microsoft.azure.credentials.ApplicationTokenCredentials生成访问令牌以管理Azure资源，但编译时遭遇了未知错误。以下是相关信息及排查建议：

本地Java版本 #

java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

POM依赖（提供的片段不完整） #

<dependencies>
    <dependency>
        <groupId>com.microsoft.azure</groupId>
        <artifactId>azure</artifactId>
        <version>1.10.0</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
    <dependency>
        <groupId>com.microsoft.azure</groupId>
        <artifactId>adal4j</artifactId>
        <version>

排查建议 #

1. 补全并修正POM依赖 #

你提供的adal4j依赖片段没有填写版本号且标签未闭合，这会直接导致Maven无法正确解析依赖。根据Azure SDK 1.10.0的兼容版本，建议使用adal4j 1.6.3版本，完整配置如下：

<dependency>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>adal4j</artifactId>
    <version>1.6.3</version>
</dependency>

2. 明确指定Maven编译器版本 #

Maven Compiler Plugin 3.1默认可能未绑定Java版本，虽然你本地是Java 8，但最好在POM中明确指定source和target版本，避免编译时版本不匹配：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

3. 清理Maven缓存并重新构建 #

有时候本地Maven依赖缓存损坏会导致奇怪的编译问题，执行以下命令强制更新依赖并重新构建：

mvn clean install -U

4. 检查代码中的语法错误 #

日志只显示“未知编译问题”，大概率是代码中存在语法错误，比如：

• 错误导入ApplicationTokenCredentials类
• 调用该类构造方法或方法时参数不匹配
• 遗漏必要的import语句
  仔细检查使用ApplicationTokenCredentials的代码部分，确认语法和调用逻辑正确。
