AWS 開發工具包：java.lang.NoSuchMethodError

Question

每當我嘗試通過 AWS 開發工具包發送郵件時，都會出現以下異常：

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

我在這里得到了一個提示（ https://github.com/aws/aws-sdk-java/issues/422 ）什么可能是錯的：顯然 HttpClient 和 HttpCore 的版本之間存在一些沖突，但我無法弄清楚無論我嘗試哪個版本。

.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"/

此異常是由以下代碼行引起的：

AmazonSimpleEmailServiceClient client = new AmazonSimpleEmailServiceClient(credentials);

其中credentials是 AWSCredentials 的一個實例。
如果您需要任何其他信息，我將很樂意提供。

Answer 1

確保您的核心版本和 s3 版本相同。

我收到了 beforeClientExecution 的 java.lang.NoSuchMethodError

這對我有用

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

Answer 2

有同樣的問題。 我的解決方案是升級我的 AWS 版本

<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-s3</artifactId>

在 pom.xml 從<version>1.10.77</version>到<version>1.11.192</version>

Answer 3

我面臨着同樣的問題。我能夠通過讓我的 httpClient 的訂單成為我的頂級 jar 來解決它在 Project-> RightCLick->Java BuildPath->Order and Export

Answer 4

嘗試使用以下命令為您的項目獲取 maven 依賴樹，然后確保 aws sdk 核心和 s3 版本相同。

mvn dependency:tree -Dincludes=com.amazonaws

示例：我的項目的依賴樹，我在其中使用 aws sdk for java 2。如您所見，核心版本和 dynamodb 版本是同步的。

mvn dependency:tree -Dincludes=software.amazon.awssdk
