aws cdk 入门 - `cdk synth` 命令的“空”output

Question

我正在尝试按照官方教程进行操作： https://docs.aws.amazon.com/cdk/latest/guide/getting_started.html

我选择了 Java，但也尝试了 Typescript，结果相同：未生成 S3 存储桶资源模板，并且部署未创建存储桶。

代码在这里： https://github.com/jumarko/aws-experiments/tree/master/cdk/hello-cdk-java

cdk synth命令只产生这个CDKMetadata而没有别的：

cd hello-cdk-java

cdk init app --language java

mvn compile

cdk ls

# modify the stack java code
...

# this for some reason only outputs Metadata for me
# even `mvn clean package` doesn't help
cdk synth

关于发生了什么或如何调试问题的任何线索？

我正在使用具有以下 CLI 版本的 Mac OS X 10.15.6：

$ aws --version
aws-cli/2.0.10 Python/3.8.2 Darwin/19.6.0 botocore/2.0.0dev14

$ cdk --version
1.61.1 (build 347918f)

我从模板生成了一个新项目，它突然开始工作了。 我不确定发生了什么变化 - 我也尝试使用不同--profile但起初也没有用。

现在问题已解决 - 如果出现问题，值得从头开始！
