java - How to Exclude properties file from jar file? -

-

i have java application following project structure:

myproject   |   |----src   |     |   |     |--main   |     |   |     |--resources   |           |      |           |--userconfig.properties   |           |--log4j.properties   |   |---target

i using maven build project. using maven command build jar file follows:

mvn package -dmaven.test.skip=true

i want exclude userconfig.properties file jar file have updated pom.xml follows:

<excludes>     <exclude>**/userconfig.properties</exclude> </excludes>

but excludes target folder in compiled code resides. , application won't run because unable find userconfig.properties file.

can me?

i encountered scenario well. basically, want able run code locally eclipse using userconfig.properties file readily accessible, such inside /src/main/resources. additionally, want provide compiled executable jar external userconfig.properties allows user configure application without cracking jar.

my implementation follows: running mvn clean install will:

  • create executable jar specified mainclass
  • exclude .properties files located in src/main/resources jar
  • copy project dependencies lib folder in project root
  • copy .properties files located in src/main/resources conf folder in project root. note step optional convenience users of jar. can require explicitly create file in conf directory. conf directory added runtime classpath via manifest.
  • add conf folder manifest, providing access executable jar

using these maven plugins in conjunction each other in pom configuration give need. "best practices" of solution; i'm not sure.

using maven-dependency-plugin follows:

<plugin>   <groupid>org.apache.maven.plugins</groupid>   <artifactid>maven-dependency-plugin</artifactid>   <executions>     <execution>       <id>copy-dependencies</id>       <phase>prepare-package</phase>       <goals>         <goal>copy-dependencies</goal>       </goals>       <configuration>         <outputdirectory>${project.build.directory}/lib</outputdirectory>         <overwritereleases>false</overwritereleases>         <overwritesnapshots>false</overwritesnapshots>         <overwriteifnewer>true</overwriteifnewer>       </configuration>     </execution>   </executions> </plugin>

using maven-jar-plugin follows:

<plugin>   <groupid>org.apache.maven.plugins</groupid>   <artifactid>maven-jar-plugin</artifactid>   <version>2.3</version>   <configuration>     <excludes>       <exclude>**/*.properties</exclude>     </excludes>                         <archive>       <manifest>         <addclasspath>true</addclasspath>         <classpathprefix>lib/</classpathprefix>         <mainclass>package.path.to.your.main.class.mainclass</mainclass>       </manifest>       <manifestentries>         <class-path>conf/</class-path>       </manifestentries>     </archive>   </configuration> </plugin>

using maven-resources-plugin follows:

<plugin>   <groupid>org.apache.maven.plugins</groupid>   <artifactid>maven-resources-plugin</artifactid>   <version>2.3</version>   <executions>     <execution>       <id>copy-resources</id>       <phase>install</phase>       <goals>         <goal>copy-resources</goal>       </goals>       <configuration>         <outputdirectory>${basedir}/target/conf</outputdirectory>         <resources>           <resource>             <directory>src/main/resources</directory>             <includes>               <include>**/*.properties</include>             </includes>           </resource>         </resources>       </configuration>     </execution>   </executions> </plugin>

using project setup, can run in eclipse using 1 config, , provide users properties file configure, without properties stepping on each other.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
