Quoting and escaping in Maven Exec plugin -

-

how quoting , escaping work parameters passed maven plugins?

for example want pass multiple filenames arguments application run maven exec plugin:

mvndebug exec:java -dexec.mainclass="main" -dexec.args="/path/to/file1 /path/to/file2"

but if paths have spaces?

i've tried using \":
-dexec.args="\"/path/to/a file\" /path/to/file2"

and "":
-dexec.args="""/path/to/a file"" /path/to/file2"

neither works :-(. neither moving first quote before -d.

the source code maven exec plugin doesn't me either, receives string[] somewhere, where?

note must work command line, without changes pom file.

you try single quotes (') doubt work, either.

the problem can have several argument elements inside pom (hence array in plugin's source) have single property command line.

options:

  • patch plugin and/or open feature request support several arguments (maybe exec.args.0, exec.args.1, exec.args.2, ...)

  • create module depends on project/module , can change pom

  • use ant or bash script. use approach collect useful commands aren't supported maven. mvn dependency:build-classpath -dmdep.outputfile=... give classpath in case.
