Amazon web services aws cdk入门-“；“空的”；“cdk synth”命令的输出

我正在尝试遵循官方教程：

我选择了Java，但也尝试了Typescript，结果相同：没有生成S3 bucket资源模板，部署也没有创建bucket

代码如下：

cdk synth

命令只生成此

CDKMetadata

而不生成其他内容：

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

关于发生了什么或者如何调试这个问题有什么线索吗

我正在使用Mac OS X 10.15.6和以下CLI版本：

$ 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)

---

我根据模板生成了一个新项目，它突然开始工作。 我不确定是什么改变了-我也尝试过使用不同的

--profile

，但一开始也不起作用

现在问题解决了——如果出了什么问题，重新开始是值得的
