问题

将Square Okhttp Logging Interceptor library添加到我的Kotlin应用程序后，我遇到以下错误，我认为这可能是由于Guava依赖项冲突引起的。我也filed an issue在Square的图书馆中。

错误

重建Jar工件。
重建项目。
使IntelliJ缓存无效并重新启动IDE。
重新同步Gradle文件。
明确定义 guava 和 com.google.api 库。
从库中排除 guava 的旧版本。（dependency scan）

Answer 1

以我为例，我安装了日志记录拦截器（3.13.1）

    <dependency>
        <groupId>com.squareup.okhttp3</groupId>
        <artifactId>logging-interceptor</artifactId>
        <version>3.13.1</version>
    </dependency>

使用 okhttp（3.13.1）

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>3.13.1</version>
</dependency>

和我的改造（2.5.0）

<dependency>
    <groupId>com.squareup.retrofit2</groupId>
    <artifactId>retrofit</artifactId>
    <version>2.5.0</version>
</dependency>

哪个用户 okhttp（3.12.0）

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>3.12.0</version>
</dependency>

由于日志拦截器的顺序（或其他） okhttp 依赖性被忽略。我猜 okhttp（3.12.0）与日志记录拦截器（3.13.1）不兼容。

Answer 2

我发现了同样的问题，只是将logging-interceptor添加到gradle会使应用程序崩溃。

我尝试了不同的版本：3.13.1和3.14.2，但目前看来只有4.0.0-alpha2可以解决此问题：

implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.okhttp3:logging-interceptor:4.0.0-alpha02'

NoClassDefFoundError：方形记录拦截器v3.12.0
