実現したいこと

Androidアプリでminioのサーバにファイルをアップロードしたい．

前提

AWSのライブラリを使用するのが正しいのかminioのライブラリを使用するのが正しいのかがわからないので両方トライしています．
この質問はminioのライブラリを使用する方の質問です．
以下を参考にコードを書いています．
https://min.io/docs/minio/linux/developers/java/minio-java.html

AWSの方でもエラーが発生しています．それはこの質問になっています．

発生している問題・エラーメッセージ

E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

該当のソースコード

kotlin

2
3import io.minio.MinioClient
4import io.minio.UploadObjectArgs
5
6class MinioClient {
7

13    fun postFile(pass: String) {
14        val minioClient = MinioClient.builder()
15            .endpoint(endpoint)
16            .credentials(accessKey, secretKey)

21                .bucket(bucketName)
22                .`object`("sample.csv")
23                .filename(pass)
24                .build()
25        )
26    }
27}

試したこと

Failed resolution of: Ljavax/xml/stream/XMLInputFactory
このエラーはjavax.xml.streamパッケージが存在しないため発生していると思ったので．
implementation 'javax.xml.stream:stax-api:1.0-2'
これをimportしました．
しかしこれは以下のエラーを出します．

FATAL EXCEPTION: OkHttp Dispatcher
Process: com.example.s3client, PID: 13955
 javax.xml.stream.FactoryConfigurationError: Provider 
 com.bea.xml.stream.MXParserFactory not found
 at javax.xml.stream.FactoryFinder.newInstance(FactoryFinder.java:72)
 at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:176)

このProvider com.bea.xml.stream.MXParserFactory not foundの対策として
implementation group: 'stax', name: 'stax-api', version: '1.0.1'
implementation group: 'stax', name: 'stax', version: '1.2.0'
を追加しました．
しかしこれは競合を起こしました．
なので最終的に

gradle
1    implementation 'androidx.core:core-ktx:1.9.0'
2    implementation 'androidx.appcompat:appcompat:1.6.0'
3    implementation 'com.google.android.material:material:1.8.0'
4    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
5    testImplementation 'junit:junit:4.13.2'
6    androidTestImplementation 'androidx.test.ext:junit:1.1.5'
7    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
8    implementation 'io.minio:minio:8.5.1'
9    implementation 'javax.xml.stream:stax-api:1.0-2'
10    implementation ('org.simpleframework:simple-xml:2.7.1'){
11        exclude module: 'stax'
12        exclude module: 'stax-api'
13        exclude module: 'xpp3'
14    }

このようにしました．しかしこれは多くの競合のエラーを出します．

自己解決

解決法

こいつをgradleに追加
implementation group: 'org.apache.openejb', name: 'javaee-api', version: '6.0-1'

で，こいつは他のライブラリが参照しているリソースを参照してしまうため
例（jetified-javaee-api-6.0-1.jarおよびjetified-geronimo-servlet_3.0_spec-1.0-sources.jar）が同じリソース
これを一つづつexcludeします．

packagingOptions {
pickFirst 'META-INF/services/javax.xml.stream.XMLInputFactory'
exclude 'javax/servlet/jsp/resources/jspxml.xsd'
exclude 'javax/servlet/jsp/resources/web-jsptaglibrary_2_0.xsd'
exclude 'javax/servlet/jsp/resources/web-jsptaglibrary_2_1.xsd'
exclude 'javax/servlet/http/LocalStrings_ja.properties'
exclude 'META-INF/mimetypes.default'
exclude 'javax/servlet/resources/web-app_2_4.xsd'
exclude 'javax/servlet/jsp/resources/web-jsptaglibrary_1_2.dtd'
exclude 'javax/servlet/resources/j2ee_web_services_client_1_1.xsd'
exclude 'javax/servlet/http/LocalStrings_fr.properties'
exclude 'javax/servlet/LocalStrings_ja.properties'
exclude 'javax/servlet/jsp/resources/web-jsptaglibrary_1_1.dtd'
exclude 'javax/servlet/http/LocalStrings_es.properties'
exclude 'javax/servlet/resources/xml.xsd'
exclude 'javax/servlet/http/LocalStrings.properties'
exclude 'javax/servlet/resources/XMLSchema.dtd'
exclude 'javax/servlet/resources/j2ee_web_services_1_1.xsd'
exclude 'javax/servlet/resources/web-app_2_2.dtd'
exclude 'javax/servlet/resources/j2ee_1_4.xsd'
exclude 'META-INF/DEPENDENCIES'
exclude 'javax/servlet/resources/web-app_2_5.xsd'
exclude 'javax/el/LocalStrings.properties'
exclude 'javax/servlet/jsp/resources/jspxml.dtd'
exclude 'javax/servlet/resources/datatypes.dtd'
exclude 'javax/servlet/jsp/resources/jsp_2_0.xsd'
exclude 'javax/servlet/LocalStrings_fr.properties'
exclude 'javax/servlet/LocalStrings.properties'
exclude 'javax/servlet/jsp/resources/jsp_2_1.xsd'
exclude 'javax/servlet/resources/web-app_2_3.dtd'
}

するとOkHttpライブラリに関連する問題が発生します．
Requested factory com.ctc.wstx.stax.WstxInputFactory cannot be located

なのでWstxInputFactoryを追加します．
// https://mvnrepository.com/artifact/com.fasterxml.woodstox/woodstox-core
implementation 'com.fasterxml.woodstox:woodstox-core:6.5.0'

動きます．
