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>
