The File or extention is too long

[ionic egret]

Hey Everyone,

I'm facing this issue which says the file or extention is too long while I'm trying to run my project, I'm working on windows and try everything regarding long path but not working

[turbid vortex]

<@&1004656351647117403> please have a look, thanks.

[undone rose]

hello

it seems you're using springboot maven plugin to run a java program

[ionic egret]

Yes

[undone rose]

alright, first u need to make sure the project compiles

./mvnw clean install

[ionic egret]

It's not working

[undone rose]

tht means u have errors in your project that must be solved before u run it

[ionic egret]

but wile I'm trying to run

mvn spring-boot:run -Pdev

on my macbook, it's working and running

[ionic egret]

facing issue in windows machine

[undone rose]

huh

maybe you have wrong JDK

[junior drum]

Then try to shorten the path
Never had this issue tho 🤔

[foggy chasm]

Well you can run code even if tests fail.

[foggy chasm]

What?

@ionic egret you're running into windows path length issues, can you share your pom file?

[undone rose]

it's possible tht jdk installed is not suitable with spring boot

the guy says that on apple same code works

[foggy chasm]

What?

There have been very few OS specific bugs.

[undone rose]

What

Spring Boot 3.0 requires Java 17 as a minimum version

if they use lower version, they may have issues

i agree to share the pom file content so we know the setup

[foggy chasm]

That is not OS related and would lead to a different issue.

[undone rose]

but also, let us know about your installed JDK @ionic egret

[undone rose]

it is

as long as jdk install is in os

[foggy chasm]

Sigh.

This is an OS related issue, not a JDK one.

[ionic egret]

I'm using JDK17

[foggy chasm]

Where is your .m2 folder located?

[ionic egret]

C:\Users\Arundhati Hazra.m2

C:\Users\Arundhati Hazra\ .m2

[foggy chasm]

can you do mvn -X spring-boot:run and check for forked process?

There are a couple of options, likely the easiest is moving your .m2 folder to the root if that pops something up. Given those dependenies you might be dragging something quite long in.

[undone rose]

Alright

Try to do

./mvnw clean install -U

It seems u have some corrupted dependencies

If that doesn't solve it, then try to delete all dependencies in m2

Then retry

Also, is there a settings.xml file inside m2?

[undone rose]

Do u have test classes in ur spring boot?

The error says spring context failed to load for testclass

I think that's the problem

[ionic egret]

There is no setting.xml file in that folder

[foggy chasm]

No.

The reason that test fails is the same as why they can't run it.

[ionic egret]

Okay, what would be the solution

[foggy chasm]

Still at work, I just had a short coffee break but just check what I asked earlier in regards to the classpath length.

[ionic egret]

What class path?

You didn't mentioned

[foggy chasm]

#1275369200596291625 message

And below.

The .m2 recommendation is more likely to help.
But I have to return to work.

[ionic egret]

Okay let me try with -X

[ionic egret]

Okay

[undone rose]

Can u do ./mvnw spring-boot:run -DskipTests

If the works with this command

That means the problem is only in tests

[lean merlin]

the issue is not a malformed test firas

it is bc the paths are too long

windows has a path limit of 255 characters

unless wide-paths are enabled

so if u happen to construct a file-path that is longer than that, windows says nope

[undone rose]

Never saw this

[ionic egret]

Let me try

[lean merlin]

then id suggest u step back and let the people who know about this issue handle the situation

🙂

u can see it being reported clearly here: https://i.imgur.com/BXgYeEB.png

[ionic egret]

Same

[lean merlin]

so maven failed to launch the entire setup as something in the chain of actions is too long for windows

so we have to find the something

[ionic egret]

So there must be solution for that

[lean merlin]

helpers suspected something in the pom and especially the .m2 where it would load external deps from

especially .m2 can easily create very long paths with deeply nested dependencies

for example, if ur .m2 is installed in a path that is already a bit longer, lets say C:/Users/John/Foo/Bar/Baz/Bblabla/.m2 and then u have a dependency in there with a long name, lets say

[ionic egret]

It's not looks so long

[undone rose]

Hmm it's possible that a directory name with space between like "my directory" may behind this?

[lean merlin]

com/spring/boot/foo/bar/baz/

then the entire path to down there is very long:

C:/Users/John/Foo/Bar/Baz/Bblabla/.m2/com/spring/boot/foo/bar/baz/

and can easily outrun windows limit of 255 characters

in which case it all breaks

[ionic egret]

But it's short

[lean merlin]

well, ur name isnt that short to be fair

[ionic egret]

This is the play where m2 file located

[lean merlin]

there could be other offenders than just m2 though

it was just one (common) source for this

[ionic egret]

So what should I do

[lean merlin]

to make sure its not the m2, u could move it to a top level directory instead

such as C:/.m2

that would give u like 30 more characters room

otherwise u can also try to enable windows wide-path mode

or continue searching for other offenders in ur maven setup

also, are u sure the actual path is short?

it seems like ur launching from mingw

[ionic egret]

Just moved that folder to c:/ ?

[lean merlin]

so if its virtual filesystem is somewhere deeper down the file paths, the actual file path on ur windows system would be very long

like, mingws /d/surely-insurance-core/partner might actually be C:/Users/John/Foo/bar/Baz/Boo/baba/blabla/blabla/mingw/deepdown/filesystem/d/surely-insurance-core/partner

if u get what i mean

[lean merlin]

u would also have to adjust ur maven settings

u cant just move the folder around and expect it to find it still

[foggy chasm]

That's literally the first thing I said here.

[foggy chasm]

* Move .m2 repository to c:\
* Open settings.xml from %MAVEN_HOME%/conf and look for \<settings>.\<localRepository>(uncomment it if its commented out already) and change its value to c:/.m2/repository
* Save the file and run the build again

[ionic egret]

But it has no setting.xml file in that m2 folder

[south plank]

settings.xml from %MAVEN_HOME%/conf

[lean merlin]

ur looking in the wrong folder

btw, here is how to hack windows to accept longer file paths as well: https://www.howtogeek.com/266621/how-to-make-windows-10-accept-file-paths-over-260-characters/

[foggy chasm]

Speaking from experience, that still has its quirks, but it's indeed a nice start.

[ionic egret]

I already did that

It's not working

[lean merlin]

okay. then try the m2 thing instead

[ionic egret]

Now let me try this

[lean merlin]

👍

[ionic egret]

Is it correct?

What path should I change

I have to command out these lines, right?

[foggy chasm]

Uncomment it, and change the path value (the one currently saying path to local).

[ionic egret]

Okay?

[foggy chasm]

Yes.

[ionic egret]

Now it's downloading plugins again

Let's hope for the best

[ionic egret]

Guys it's still not working

😕😕

[south plank]

still same error?

[foggy chasm]

And you restarted your computer right?

[undone rose]

did u try to delete all ur maven dependencies in m2 ?

[undone rose]

i mean: i didn't see such issue on windows during years

[south plank]

its known though

and he told about it

and it just got ignored

[ionic egret]

Yes

[ionic egret]

Mee too

Just facing these

[undone rose]

tht's why i doubt it's cuz of os

[undone rose]

can u send the logs please ?

i mean copy/paste not all of it

just the last 10 lines

also, i'd suggest u to create a second springboot project with https://start.spring.io/

without any dependency

and try to install and run it locally

in order to be certain that it's general issue on ur machine

[ionic egret]

Okay will try

Any more suggestions

[undone rose]

the problem is

in this "Program Files"

that space causes the issue

do u use a maven wrapper? ?

[ionic egret]

Yes tried wrapper, but it didn't worked

[undone rose]

in my end, when use same command as u , i dnt see that path to jdk

[south plank]

eh? did you actually read the error?

[foggy chasm]

The wrapper works just fine with spaces...

[crisp ivy]

have you tried running with the longClasspath flag set to true?

https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry

seems like you can edit it within GP

https://github.com/graalvm/native-build-tools/issues/85#issuecomment-871557663

@ionic egret

[sweet eagle]

I've noticed bad things happen when you have a space in your user name on windows. Arguments get split on that space character and shift the argument list. You have to turn on the most explicit logging.

Or try wsl

[foggy chasm]

I see you're running it from intellij, what you can also try is within your run configuration check shorten command line and then select the apt value in your configuration.

[crisp ivy]

its not an issue with maven. they use quotes for their command, so spaces are fine

[ionic egret]

Okay I will try tomorrow, today it's too late here at india

[ionic egret]

Okay I will check

Thank you guys
