Gradle复合构建下Quarkus CDI注入失败问题求助

我在使用Gradle 8和Quarkus 2.16.2.Final做复合构建时碰到了CDI注入问题：

• 库模块中定义了@ApplicationScoped的AuthTokenProvider Bean
• 服务模块的AuthTokenConsumer通过构造函数注入该Bean
• 运行应用或执行测试时，均抛出UnsatisfiedResolutionException，提示找不到该Bean的实现

已尝试的解决操作：

• 在库模块src/main/resources/META-INF目录下添加了beans.xml
• 在库模块的构建脚本中配置了Quarkus Jandex插件生成索引

但问题仍未解决，以下是完整代码、错误信息、构建配置及复现结构：

代码示例 #

库模块：AuthTokenProvider #

package com.example.lib;

import jakarta.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class AuthTokenProvider {
    public String generateToken() {
        return "dummy-token-123";
    }
}

服务模块：AuthTokenConsumer #

package com.example.service;

import com.example.lib.AuthTokenProvider;
import jakarta.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class AuthTokenConsumer {
    private final AuthTokenProvider tokenProvider;

    // 构造函数注入
    public AuthTokenConsumer(AuthTokenProvider tokenProvider) {
        this.tokenProvider = tokenProvider;
    }

    public String getToken() {
        return tokenProvider.generateToken();
    }
}

库模块beans.xml #

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="https://jakarta.ee/xml/ns/jakartaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/beans_3_0.xsd"
       version="3.0"
       bean-discovery-mode="all">
</beans>
