java模块找不到包

Question

我对自己制作的 API 使用 Retrofit 2，并使用 Retrofit gson 将 API 响应转换为对象。我有一个包含 JSON 模型的包（作为类），并且我需要 gson 来访问这些模型，但是当我添加行来打开 gson 的包时。我在建筑物上收到一个错误，说他们无法访问该包，所以我尝试打开上面的包（我知道它可以工作，因为 javafx.fxml 使用它），但后来我收到了此错误（不在建筑物上）但是当我在运行时使用 gson 时）

这是我的模块-info.java

module fr.plaglefleau.banksystemdesktop {
    requires javafx.controls;
    requires javafx.fxml;
    requires kotlin.stdlib;
    requires TranslationLibrary.main;
    requires kotlinx.coroutines.core;
    requires org.jetbrains.annotations;
    requires retrofit2;
    requires retrofit2.converter.gson;
    requires com.google.gson;

    opens fr.plaglefleau.banksystemdesktop to javafx.fxml, retrofit2.converter.gson;
    exports fr.plaglefleau.banksystemdesktop;
}

我在GitHub上推送了项目，这是链接

我尝试在 module-info.java 中添加一行来访问我的模型所在的包，但我在建筑物上收到一个错误，说它找不到该包，所以我在上面打开它套餐

Answer 1

根异常中已经提供了解决方案（强调我的）：

原因：java.lang.reflect.InaccessibleObjectException：无法 将字段设置为 private Final java.lang.String fr.plaglefleau.banksystemdesktop.api.models.bankapi.response.get.LoginResponse.message 可访问：模块 fr.plaglefleau.banksystemdesktop 无法“打开” fr.plaglefleau.banksystemdesktop.api.models.bankapi.response.get”到 模块 com.google.gson

换句话说，您需要修改您的

module-info.java

并添加以下

opens

语句。

opens fr.plaglefleau.banksystemdesktop.api.models.bankapi.response.get 
        to com.google.gson;
