Windows: Metafix-Runner sometimes complains that file path of runner is too long

[TobiasNx]

We have not found a solution yet.

$ C:\Users\USER\Downloads\metafix-runner-1.1.2\metafix-runner-1.1.2\bin\metafix-runner.bat
Die eingegebene Zeile ist zu lang.
Syntaxfehler.

Same for:

$ C:\Users\USER\Downloads\metafix-runner-1.1.2\metafix-runner\bin\metafix-runner.bat
$ C:\Users\USER\Downloads\metafix-runner\metafix-runner\bin\metafix-runner.bat
$ C:\Users\USER\Downloads\metafix-runner\metafix-runner-1.1.2\bin\metafix-runner.bat
$ C:\Users\USER\Downloads\metafix-runner-1.1.2\bin\metafix-runner.bat

The following works:

$ C:\Users\USER\Downloads\metafix-runner\bin\metafix-runner.bat
$ C:\Users\USER\Desktop\metafix-runner\bin\metafix-runner.bat

Workaround is to extract the metafix-runner without version in the download folder, the desktop or in the homefolder (maybe then with version would work too)

Installed version of Metafacture Core works:

PS C:\Users\USER\git\metafacture-core> c:\Users\USER\git\metafacture-core\metafacture-runner\build\install\metafacture-core\flux.bat c:\Users\USER\Downloads\playground.flux

Release distribution seems to work too:

PS C:\Users\User\Downloads\metafacture-core-6.1.2-dist\metafacture-core-6.1.2-dist> C:\Users\User\Downloads\metafacture-core-6.1.2-dist\metafacture-core-6.1.2-dist\flux.bat

From Fix repo:

BUILD SUCCESSFUL in 1s

but:

./gradlew.bat :metafix-runner:run 

and

./gradlew :metafix-runner:run 

Have some kind of error, at first the seem to work and output the flux commands. But the build results in an error:

PS C:\Users\User\git\metafacture-fix> ./gradlew :metafix-runner:run

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.10.2/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Have some kind of error, at first the seem to work and output the flux commands. But the build results in an error:

So do the batch scripts. Flux exits with an error code when no file is given.

[blackwinter]

The difference between Metafix and Core is that the latter provides a bespoke batch script, while the former generates a generic one via Gradle's Application plugin. This error may theoretically hit both in the same way, but the Metafix script already contains a pretty long CLASSPATH variable which includes the path to the application directory (APP_HOME) a bunch of times, thus easily exceeding the command-line string limitation.

In addition to that, the Metafix runner doesn't support the same configuration options as the Core runner (namely, java-options.conf).

Both differences may hopefully become moot once Metafix gets integrated into Core.

Tested with the metafix-runner.bat in Windows: set the classpath with wildcard set CLASSPATH=%APP_HOME%\lib\* (Flux ran without the error message). But I don't know whether this could cause problems elsewhere

@maipet right, if you manipulate metafix-runner.bat that change would be overwritten next time someone invokes gradle's application plugin, e.g. by running ./gradlew distZip. in ffa5b7a I followed https://stackoverflow.com/questions/32088966/gradle-generated-startscript-for-windows-produces-input-line-is-too-long for a solution.
