java - AWS SDK : java. lang.NoSuchMethodError

Question

每当我尝试通过 AWS SDK 发送邮件时，我都会收到以下异常:

java.lang.NoSuchMethodError: org.apache.http.params.HttpConnectionParams.setSoKeepalive(Lorg/apache/http/params/HttpParams;Z)V

我在这里得到一个提示 ( https://github.com/aws/aws-sdk-java/issues/422 ) 可能出了什么问题:显然 HttpClient 和 HttpCore 的版本之间存在一些冲突，但无论我尝试哪个版本我都无法弄清楚。

.classpath 文件的一部分:

<classpathentry kind="lib" path="lib/aws-java-sdk-1.10.69-javadoc.jar"/>
<classpathentry kind="lib" path="lib/aws-java-sdk-1.10.69-sources.jar"/>
<classpathentry kind="lib" path="lib/aws-java-sdk-1.10.69.jar"/>
<classpathentry kind="lib" path="lib/aws-java-sdk-flow-build-tools-1.10.69.jar"/>
<classpathentry kind="lib" path="lib/httpclient-4.3.6.jar"/>
<classpathentry kind="lib" path="lib/httpcore-4.3.3.jar"/>
<classpathentry kind="lib" path="lib/google-http-client-1.18.0-rc.jar"/>
<classpathentry kind="lib" path="lib/google-http-client-appengine-1.18.0-rc.jar"/>
<classpathentry kind="lib" path="lib/google-http-client-gson-1.18.0-rc.jar"/>
<classpathentry kind="lib" path="lib/google-http-client-jackson2-1.18.0-rc.jar"/>
<classpathentry kind="lib" path="lib/google-http-client-jdo-1.18.0-rc.jar"/>
<classpathentry kind="lib" path="lib/httpmime-4.1.3.jar"/

完成异常 printStack():

此异常是由以下代码行引起的:

AmazonSimpleEmailServiceClient client = new AmazonSimpleEmailServiceClient(credentials);

其中 credentials 是 AWSCredentials 的一个实例。
如果您需要任何其他信息，我很乐意提供。

Answer 1

确保您的核心版本和 s3 版本相同。

我得到了 beforeClientExecution 的 java.lang.NoSuchMethodError

这对我有用

compile('com.amazonaws:aws-java-sdk-core:1.11.376')
compile('com.amazonaws:aws-java-sdk-s3:1.11.376')
