Minio依赖冲突

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    io.minio.S3Base.<clinit>(S3Base.java:105)

The following method did not exist:

    okhttp3.RequestBody.create([BLokhttp3/MediaType;)Lokhttp3/RequestBody;

The method's class, okhttp3.RequestBody, is available from the following locations:

    jar:file:/D:/repository/com/squareup/okhttp3/okhttp/3.14.9/okhttp-3.14.9.jar!/okhttp3/RequestBody.class

The class hierarchy was loaded from the following locations:

    okhttp3.RequestBody: file:/D:/repository/com/squareup/okhttp3/okhttp/3.14.9/okhttp-3.14.9.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of okhttp3.RequestBody

因为minio底层要依赖okhttp进行和minio服务端进行通信，由于项目中多个依赖底层都依赖了不同版本的okhttp，导致这里的okhttp因版本不同，某些方法不可用，尝试降级minio的版本。

如果要用最新版，请加入下面依赖：

		<dependency>

            <groupId>com.squareup.okhttp3</groupId>

            <artifactId>okhttp</artifactId>

            <version>4.9.0</version>

        </dependency>
