AWS开发工具包：java.lang.NoSuchMethodError

Question

每当我尝试通过AWS SDK发送邮件时，我都会遇到以下异常：

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

我在这里得到了一个提示（https://github.com/aws/aws-sdk-java/issues/422）可能有什么问题：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，我都无法弄明白。

.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。

有同样的问题。我的解决方案是升级我的AWS版本

def check_events(ai_settings,stats,play_button,screen,ship,aliens,bullets):
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            sys.exit()
        elif event.type==pygame.KEYDOWN:
            check_keydown_events(event,ai_settings,screen,ship,bullets)         
        elif event.type==pygame.KEYUP:
            check_keyup_events(event,ship)
        elif event.type==pygame.MOUSEBUTTONDOWN:
            mouse_x,mouse_y=pygame.mouse.get_pos()
            check_play_button(ai_settings,screen,ship,aliens,bullets,stats,play_button,mouse_x,mouse_y)

def check_play_button(ai_settings,screen,stats,play_button,ship,aliens,bullets,mouse_x,mouse_y):
    button_clicked=play_button.rect.collidepoint(mouse_x,mouse_y)
    if button_clicked and not stats.game_active:
        pygame.mouse.set_visible(False)
        stats.reset_stats()
        stats.game_active=True
        aliens.empty()
        bullets.empty()
        create_fleet(ai_settings,screen,ship,aliens)
        ship.center_ship()

pom.xml中的

从<groupId>com.amazonaws</groupId> <artifactId>aws-java-sdk-s3</artifactId> 到<version>1.10.77</version>

Answer 2

确保您的核心版本和s3版本相同。

我在获取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')

Answer 3

我遇到了同样的问题。我能够通过制作我的JustClip of httpClient并使其成为Project-＆gt;中的顶级jar来解决它。 RightCLick-＆gt; Java BuildPath-＆gt;订单和导出

Answer 4

尝试使用以下命令为您的项目获取 maven 依赖树，然后确保 aws sdk 核心和 s3 版本相同。

mvn dependency:tree -Dincludes=com.amazonaws

示例：我使用 aws sdk for java 2 的项目的依赖树。如您所见，核心版本和 dynamodb 版本是同步的。

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