Invalid meta-data if Sagan does not provide a default boot version

[tan9]

I can not create new Spring Boot Starter projects from my IDE:

IntelliJ IDEA:

STS:

And I paste the full url generated by STS:
http://start.spring.io/starter.zip?name=demo&groupId=com.example&artifactId=demo&version=0.0.1-SNAPSHOT&description=Demo+project+for+Spring+Boot&packageName=com.example&type=maven-project&packaging=jar&javaVersion=1.8&language=java

to browser, I got white label error page:

saying:

boot version must not be null

Investigating....

[snicoll]

I think I've fixed production and I know what is going on. Can you try again please?

[tan9]

@snicoll Both IDEs can create start projects without problem! 👍

OK so the problem was that when we released 1.4.0 we forgot to tick the default value. Sagan was giving us 4 boot versions to use but none was declared as the default. It turns out that because we don't know what the default is, we won't set it if none is provided (that's the STS issue). If no default boot version is provided in the meta-data, IJ crashes. I've created an issue in their tracker for that.

On my side, I am changing the code so that it never happens again. We'll select the first version in the list as the default if non is provided.

We an see the same issue again.
Initialization failed for 'https://start.spring.io'

The issue still remains

It works for me. That's what I'd expect given the fix in d018782 and the presence of a default version (current being true) in the current metadata:

        {
            "apiDocUrl": "http://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/api/",
            "artifactId": "spring-boot",
            "current": true,
            "generalAvailability": true,
            "groupId": "org.springframework.boot",
            "preRelease": false,
            "refDocUrl": "http://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/reference/htmlsingle/",
            "releaseStatus": "GENERAL_AVAILABILITY",
            "snapshot": false,
            "version": "2.0.3.RELEASE",
            "versionDisplayName": "2.0.3"
        }

You may have an issue, @hussain21j, but I don't think it's this one.

That error is probably due to proxy setting.

[snicoll]

@caozongpeng please see the comment just before yours.

[tonskton]

Done setting the proxy but still encountering the error.

Hi I have same problem with Intellij IDEA Ultimate 20201.1. Both windows and mac versions don`t work, @snicoll

It would appear that there's a hardcoded assumption about the format of Spring Boot's version number which is changing in 2.4 from 2.4.0.BUILD-SNAPSHOT to 2.4.0-SNAPSHOT. When this assumption is invalid, it breaks parsing of the metadata:

I've temporarily removed 2.4.0-SNAPSHOT from the versions of Spring Boot that start.spring.io will offer. This will take a little while to update. Once 2.4 is no longer offered at https://start.spring.io, things should work again in IntelliJ IDEA.

Having the same issue. Spring Initializr doesn't work.

[MirekKrenc]

I have the same issue

[DimaGilyov]

I have the same issue

[Sebastianmueller22]

For me it was a transient error. Switched my wifi off and on again and now it works. Had internet the whole time though and no proxy active

[MathlouthiKhitem]

i have this error :Initialization failed for 'https://start.spring.io' Please check URL, network and proxy settings. Error message: Cannot download 'https://start.spring.io': Connect timed out

[snicoll]

@MathlouthiKhitem this is likely to be a network problem on your end.
