ClientConfiguration clientConfig = new ClientConfiguration()

抛出：IllegalArgumentException

堆栈跟踪：

ibm-cos-java-sdk-core-1.1.0和ibm-cos-java-sdk-s3-1.1.0

我想解决这个问题。来自现场的资源：ibm-cos-java-sdk

我想使用ibm-cos-java-sdk访问IBM Cloud Object Storage。

Answer 1

看起来您没有使用正确的代码依赖项。

如果您使用的是maven，请将以下依赖项放在pom.xml

中

<dependencies>
    <dependency>
        <groupId>com.ibm.cos</groupId>
        <artifactId>ibm-cos-java-sdk</artifactId>
        <version>1.0.1</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.2</version>
        <scope>test</scope>
    </dependency>
</dependencies>

com.amazonaws.internal.config.InternalConfig.load由url = null
