Proxy for ttcli

[garyhellman]

Hi Wim Thank you for your books and ttcli I found that I needed to add a proxy to be able to use ttcli in my environment Currently, I have the proxy hardcoded in the springBootInitializrClient Bean (and hardcoded "isReachable" to be true)

I suppose I will work towards getting it from environment variables Please give suggestions and/or comments

Thanks!

I am afraid I don't really understand your question. Please only use the issue tracker for questions and issues with ttcli itself. For other questions, you might be better to post a question on stackoverflow.com.

Hi Wim, This is an issue (or question) about ttcli itself. ttcli would not work in my environment. Internet was not available... But I found that it would work if I added a proxy for the connection to start.spring.io, etc, I also eliminated the test using socket connection to start.spring.io ("isReachable" set to true)

I do not know if anyone else has had this problem, but a change to the code to use a proxy fixed it for me (and maybe others...?)

If I get a pull request together, I will submit.

Thanks again

Same issue, i'm behind a corporate proxy at work and when i run ttcli init i have this error message

Error during project generation: Unable to connect to start.spring.io. Is your internet connection enabled? Error: Connect timed out

And this is the content of ttcli.log

Can you try to download the jar from the releases page and try to run:

java -Djava.net.useSystemProxies=true -jar ttcli-1.6.2.jar init

If that does not work, you can try with:

java -Dhttp.proxyHost=10.10.10.10 -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password -jar ttcli-1.6.2.jar init

Ofcourse, using the proper values for all those settings for your own proxy server.

Not working for me

$ java -Dhttp.proxyHost=my.proxy.local -Dhttp.proxyPort=8080 -jar ttcli-1.6.2.jar init
❌ Error during project generation: Unable to connect to start.spring.io. Is your internet connection enabled?
Error: Connect timed out
$ java -Dhttp.proxyHost=my.proxy.local -Dhttp.proxyPort=8080 -Dhttps.proxyHost=my.proxy.local -Dhttps.proxyPort=8080 -jar ttcli-1.6.2.jar init
❌ Error during project generation: Unable to connect to start.spring.io. Is your internet connection enabled?
Error: Connect timed out
$ java -Djava.net.useSystemProxies=true -jar ttcli-1.6.2.jar init
❌ Error during project generation: Unable to connect to start.spring.io. Is your internet connection enabled?
Error: Connect timed out

Anyone else can try?

Looking at https://docs.spring.io/spring-boot/reference/io/rest-client.html#io.rest-client.clienthttprequestfactory.configuration, maybe this can help:

Add this bean to TamingThymeleafCliApplicationConfiguration:

	@Bean
	ClientHttpRequestFactoryBuilder<?> clientHttpRequestFactoryBuilder(ProxySelector proxySelector) {
		return ClientHttpRequestFactoryBuilder.jdk()
			.withHttpClientCustomizer((builder) -> builder.proxy(proxySelector));
	}

You will need to get the sources and compile locally for that to try. I don't have a proxy server, so I can't try it out. If that works, maybe I can add property to optionally enable or disable this.

[garyhellman]

I got source; hardcoded the proxy config - it works... I will send the snippet when I get home...this week
