Amazon swf流框架中的自动生成的代码引发语法错误

Question

我正在尝试我们的Amazon SWF流框架，但是出现以下错误，并且该项目无法编译。我正在使用maven进行依赖关系管理，并且正在从Intellij运行我的代码。

[INFO] -------------------------------------------------------------
[ERROR] /home/meow/Arena/github/ProjectX/AWS/target/generated-sources/annotations/aws/swf/B_FlowFramework/B_WithAWSFlow/EditImageActivityClient.java:[24,18] <identifier> expected
[ERROR] /home/meow/Arena/github/ProjectX/AWS/target/generated-sources/annotations/aws/swf/B_FlowFramework/B_WithAWSFlow/EditImageActivityClient.java:[24,19] = expected
[ERROR] /home/meow/Arena/github/ProjectX/AWS/target/generated-sources/annotations/aws/swf/B_FlowFramework/B_WithAWSFlow/EditImageActivityClient.java:[24,25] illegal start of type
[ERROR] /home/meow/Arena/github/ProjectX/AWS/target/generated-sources/annotations/aws/swf/B_FlowFramework/B_WithAWSFlow/EditImageActivityClient.java:[29,18] <identifier> expected
[ERROR] /home/meow/Arena/github/ProjectX/AWS/target/generated-sources/annotations/aws/swf/B_FlowFramework/B_WithAWSFlow/EditImageActivityClient.java:[29,19] = expected

从Intellij，我已经确认是否通过设置->构建，执行，部署->编译器->注释处理器-> 启用注释处理

代码库位于GitHub上，其入口点位于https://github.com/vikkyhacks/ProjectX/blob/master/AWS/src/main/java/aws/swf/B_FlowFramework/B_WithAWSFlow/WorkflowStarter.java

还添加pom.xml以便于参考，

Answer 1

这可能是因为您正在使用AWS开发工具包v1.11和JDK 1.8。您是否尝试将AWS开发工具包升级到2.0，或将JDK降级到1.6？

查看官方文档：

来自SDK 1.1：https://github.com/aws/aws-sdk-java/blob/master/README.md

要运行SDK，您需要Java 1.6+。有关SDK的要求和最佳设置的更多信息，请参见开发人员指南的Installing a Java Development Environment部分。

来自SDK 2.0：https://github.com/aws/aws-sdk-java-v2/blob/master/README.md

要运行SDK，您需要Java 1.8+。有关SDK的要求和最佳设置的更多信息，请参见开发人员指南的Installing a Java Development Environment部分。

此外，AWS recommends用于指定/包括各个模块的BOM方法：

指定各个SDK模块（推荐）要选择单个SDK模块，请使用适用于Maven的AWS开发工具包Java物料清单（BOM）。这样可以确保您指定的模块使用相同版本的SDK，并且彼此兼容。

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>software.amazon.awssdk</groupId>
      <artifactId>bom</artifactId>
      <version>2.X.X</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

以及Kinesis和DynamoDB的示例：

<dependencies>
  <dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>kinesis</artifactId>
  </dependency>
  <dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>dynamodb</artifactId>
  </dependency>
</dependencies>

注意：对于SWF，请尝试artifactId作为swf。完整清单：https://search.maven.org/search?q=g:software.amazon.awssdk
