groovy - My Gradle project depends on commons-io 2.4, but Gradle puts $GRADLE_HOME/commons-io-1.4.jar into the classpath, causing failures -


i've been iterating on features in first gradle plugin. determined on needed commons-io, added dependency on commons-io 2.4, being latest version.

this has been going while, build working command line, , no errors in eclipse.

i started trying integrate code uses "fileutils.write(file,string)". didn't need method before. got un-redded in eclipse, , tried command line build.

this failed errors following:

    ... error: cannot find symbol                 fileutils.write(serviceloaderfile,                          ^   symbol:   method write(file,string)   location: class fileutils

this confused me. went failing lines in eclipse, , no issues indicated. navigated "write()" method, , looked fine me. ran command-line build "--debug" clues.

when found "javac" line, found "$gradle_home\lib\commons-io-1.4.jar" (where "gradle_home" gradle 2.3 distribution) in classpath before dependency jar. inspected code in 1.4 jar, , determined "fileutils" class in version didn't have "write" method.

what supposed this?

update:

i suppose it's "dependencies" block useful, this:

dependencies {   compile ("org.codehaus.groovy:groovy-all:2.3.9")   compile gradleapi()   compile "org.opendaylight.yangtools:yang-parser-impl:0.7.0-snapshot"   compile "org.opendaylight.yangtools:binding-java-api-generator:0.7.0-snapshot"   compile "org.opendaylight.yangtools:binding-generator-api:0.7.0-snapshot"   compile "org.opendaylight.yangtools:binding-generator-impl:0.7.0-snapshot"   compile "org.opendaylight.controller:yang-jmx-generator:0.3.0-snapshot"   compile "commons-io:commons-io:2.4"    testcompile("org.spockframework:spock-core:1.0-groovy-2.3") {     exclude group: "org.codehaus.groovy"   }

i tried commenting out "gradleapi" reference, , had no effect. tried adding "exclude" commons-io associated "groovy-all" reference, didn't appear make difference. }

you added gradleapi() under dependencies {} block - see docs. problem ships dependencies gradle requires - including commons-io in version 1.4 - see extract below:

[opal@opal-mac-2]~/.gvm/gradle/current/lib % pwd /users/opal/.gvm/gradle/current/lib [opal@opal-mac-2]~/.gvm/gradle/current/lib % ll commons-io-1.4.jar  -rw-rw-r--  1 opal  staff  109043 23 gru 13:17 commons-io-1.4.jar [opal@opal-mac-2]~/.gvm/gradle/current/lib %

you added version 2.4 separately , that's why conflict occurred. can run

gradle dependencies

to view full dependency tree , verify problem.

there's no possibility exclude transitive dependency gradleapi().

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
