如何减少maven Jar文件大小（当前为255 MB）

Question

如何减小Maven可执行Jar文件大小。目前为255 MB。它不允许在Cloud形成中部署。

我正在通过云形成进行部署-

如果我可以将文件的大小从255 MB减少，那么我的问题就会得到解决。

我从JAR文件中看到，下面2个依赖项占用了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>

我应该怎样减少它？

Answer 1

此问题已解决，我正在使用AWS依赖项-

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

我不需要所有依赖项，我只需要S3和Lambda。因此，请删除此依赖项。它减少了我的Jar文件。255 MB到50 MB。
