java - amazon swf flow 框架中自动生成的代码抛出语法错误

Question

我正在尝试我们的亚马逊 SWF 流程框架，但出现以下错误并且项目无法编译。我正在使用 Maven 进行依赖项管理，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

在 Intellij 中，我已经确认是否从设置 -> 构建、执行中启用了注释处理， 部署 -> 编译器 -> 注释处理器 -> 启用 注解处理

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。

同时添加pom.xml方便引用，

Answer 1

这可能是因为您使用的是 AWS SDK v1.11 和 JDK 1.8。您是否尝试将 AWS SDK 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

To run the SDK you will need Java 1.6+. For more information about the requirements and optimum settings for the SDK, please see the Installing a Java Development Environment section of the developer guide.

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

To run the SDK you will need Java 1.8+. For more information about the requirements and optimum settings for the SDK, please see the Installing a Java Development Environment section of the developer guide.

此外，AWS recommends用于指定/包含单个模块的 BOM 方法:

Specifying Individual SDK Modules (Recommended) To select individual SDK modules, use the AWS SDK for Java bill of materials (BOM) for Maven. This ensures that the modules you specify use the same version of the SDK, and that they're compatible with each other.

<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，请尝试将 artifactId 作为 swf。完整列表:https://search.maven.org/search?q=g:software.amazon.awssdk
