Benjamin Bentmann commented on MNG-3529: ---------------------------------------- The problem originates from the Unix shell script we use to launch Maven, the relevant part: {noformat} QUOTED_ARGS="" while [ "$1" != "" ] ; do QUOTED_ARGS="$QUOTED_ARGS \"$1\"" shift done [...] exec [...] $QUOTED_ARGS {noformat} While I can't explain it, this screws up the parameter passing and makes {{-D=" "}} parse as the two parameters {{"-D=}} and {{"}} There seem to be two possible solutions to this: a) Nuke the QUOTED_ARGS variable and use the special variable {...@}} instead, i.e. {noformat} exec [...] "$@" {noformat} b) Mimic Ant's launch script and do {noformat} exec_cmd="exec [...] $QUOTED_ARGS" eval $exec_cmd {noformat} Personally, I don't enough about Unix shell scripting to judge which of these is preferrable or might have unwanted side effects so Unix gurus please speak up. > mvn -Da=" " throws an excepltion > -------------------------------- > > Key: MNG-3529 > URL: http://jira.codehaus.org/browse/MNG-3529 > Project: Maven 2 & 3 > Issue Type: Bug > Components: Command Line > Affects Versions: 2.0.8 > Reporter: Sean Bridges > Priority: Trivial > Fix For: 3.0-alpha-8 > > > Doing, > mvn -Da=" " > throws, > --------------------------------------------------- > java.lang.StringIndexOutOfBoundsException: String index out of range: -1 > at > java.lang.AbstractStringBuilder.setLength(AbstractStringBuilder.java:146) > at java.lang.StringBuffer.setLength(StringBuffer.java:154) > at > org.apache.maven.cli.MavenCli$CLIManager.cleanArgs(MavenCli.java:793) > at org.apache.maven.cli.MavenCli$CLIManager.parse(MavenCli.java:746) > at org.apache.maven.cli.MavenCli.main(MavenCli.java:100) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:585) > at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) > at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) > at > org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) > at org.codehaus.classworlds.Launcher.main(Launcher.java:375) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
