我如何减少maven Jar文件大小目前255mb ?

Question

如何减小Maven可执行Jar文件的大小。目前是255mb，不允许在Cloudformation中部署。

我正在通过cloudformation进行部署——>Lambda和API get .

如果我能把文件从255mb缩小，那么我的问题就解决了。

我从JAR文件中看到，以下2个依赖项占用195 MB。

<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.11.931</version>
</dependency>
<dependency>
<groupId>com.amazonaws.serverless</groupId>
<artifactId>aws-serverless-java-container-spring</artifactId>
<version>[0.1,)</version>

我应该怎么做?

问题已解决，我正在使用AWS依赖-

<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.11.931</version>
</dependency>

我不需要所有的依赖关系，我只需要S3和Lambda。所以我们要去掉这个依赖。它减少了我的Jar文件。255mb ~ 50mb
