hibernate - How do you integrate the java annotation processor into the java plugin -


i have project laid out follows:

src/ java generated

src/java contains jpa entities , query classes use jpa metamodel classes generated hibernate metamodel annotation processor.

what best way incorporate annotation processing java plugin?

i have following task defined, has task dependency on compilejava fail because of code dependent on classes generated annotation processor.

task processannotations(type: compile) { gendir = new file("${projectdir}/src/generated") gendir.mkdirs() source = ['src/java'] classpath = sourcesets.test.compileclasspath destinationdir = gendir options.compilerargs = ["-proc:only"] }

the reason why processannotations depends on compilejava put test compile class path on former task's compile class path, , test compile class path contains compiled production code (i.e. output of compilejava).

as how best solve problem @ hand, shouldn't need separate compile task. java compiler can invoke annotation processors , compile generated sources (along original sources) in 1 pass (see annotation processing). 1 thing you'll need put annotation processor on compile class path:

configurations { hibernateannotationprocessor } dependencies { hibernateannotationprocessor "org.hibernate: ..." } compilejava.compileclasspath += configurations.hibernateannotationprocessor

(you don't want add annotation processor compile configuration because considered dependency of production code.)

from can tell, there (assuming using jdk6 or higher).

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
