java - How to compile jsoup through Ant? -


i tried use ant compile jsoup source. can compile successfully, cannot pass test. here process:

jsoup version: 1.6.3 ; ant version: 1.8.2

the source of jsoup in directory

src/

i made build file

src/build.xml

this file contains

<project name="jsoup"> <target name="compile"> <mkdir dir="build/classes"/> <javac srcdir="src" destdir="build/classes" includeantruntime="false"/> </target> <target name="jar"> <mkdir dir="build/jar"/> <jar destfile="build/jar/jsoup.jar" basedir="build/classes"> <manifest> <attribute name="main-class" value="statetrace"/> </manifest> </jar> </target> <target name="run"> <!--<java jar="build/jar/jsoup.jar" input="htmls/index.html" fork="true"/>--> <exec executable="java"> <arg value="-jar"/> <arg value="build/jar/jsoup.jar"/> <arg value="htmls/index.html"/> </exec> </target> </project>

note: 1. statetrace.java own test program (as below); 2. htmls/index.html input statetrace.java.

string html; // contains content in htmls/index.html ... try{ document doc = jsoup.parse(html); }catch(ioexception e){e.printstacktrace();}

then compile , run ant:

> ant compile > ant jar > ant run

after this, got err like:

run: [exec] exception in thread "main" java.lang.exceptionininitializererror [exec] @ org.jsoup.nodes.entities$escapemode.<clinit>(unknown source) [exec] @ org.jsoup.nodes.document$outputsettings.<init>(unknown source) [exec] @ org.jsoup.nodes.document.<init>(unknown source) [exec] @ org.jsoup.parser.treebuilder.initialiseparse(unknown source) [exec] @ org.jsoup.parser.treebuilder.parse(unknown source) [exec] @ org.jsoup.parser.htmltreebuilder.parse(unknown source) [exec] @ org.jsoup.parser.parser.parse(unknown source) [exec] @ org.jsoup.jsoup.parse(unknown source) [exec] @ statetrace.main(unknown source) [exec] caused by: java.lang.nullpointerexception [exec] @ java.util.properties$linereader.readline(properties.java:418) [exec] @ java.util.properties.load0(properties.java:337) [exec] @ java.util.properties.load(properties.java:325) [exec] @ org.jsoup.nodes.entities.loadentities(unknown source) [exec] @ org.jsoup.nodes.entities.<clinit>(unknown source) [exec] ... 9 more [exec] result: 1 build successful total time: 0 seconds

however, if manually compiled java source, like

javac src/org/jsoup/*.java src/org/jsoup/parser/*.java src/org/jsoup/examples/*.java src/org/jsoup/nodes/*.java src/org/jsoup/safety/*.java src/org/jsoup/select/*.java src/org/jsoup/helper/*.java

i compile , pass test.

any clue? thanks!

this build.xml works ant 1.8.2:

<?xml version="1.0"?> <project name="jsoup"> <target name="compile"> <mkdir dir="build/classes"/> <javac srcdir="src" destdir="build/classes" includeantruntime="false"/> </target> <target name="jar"> <mkdir dir="build/jar"/> <jar destfile="build/jar/jsoup.jar" basedir="build/classes"> <manifest> <attribute name="main-class" value="org.jsoup.examples.htmltoplaintext"/> </manifest> </jar> </target> <target name="run"> <!--<java jar="build/jar/jsoup.jar" input="htmls/index.html" fork="true"/>--> <exec executable="java"> <arg value="-jar"/> <arg value="build/jar/jsoup.jar"/> <arg value="htmls/index.html"/> </exec> </target> </project>

... waiting more information ... ... until turns up, guess there no file @ htmls/index.html

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

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.
