在Java中編譯/構建項目時，將jar復制到輸出文件夾

Question

快速提問：在Java中編譯/構建項目時，如何配置NetBeans將jar文件（我的應用程序使用sqlite.jar ） output folder到output folder ？

Answer 1

使用Ant構建。 與使用ide制作jar相比，它更好

Answer 2

在NetBeans中，切換到“文件”選項卡。 展開您的項目（要構建的項目）。

雙擊build.xml 。

有許多構建目標可以覆蓋... build.xml為它們提供文檔，但這里是dump

There exist several targets which are by default empty and which can be 
used for execution of your tasks. These targets are usually executed 
before and after some main targets. They are: 

  -pre-init:                 called before initialization of project properties
  -post-init:                called after initialization of project properties
  -pre-compile:              called before javac compilation
  -post-compile:             called after javac compilation
  -pre-compile-single:       called before javac compilation of single file
  -post-compile-single:      called after javac compilation of single file
  -pre-compile-test:         called before javac compilation of JUnit tests
  -post-compile-test:        called after javac compilation of JUnit tests
  -pre-compile-test-single:  called before javac compilation of single JUnit test
  -post-compile-test-single: called after javac compilation of single JUunit test
  -pre-jar:                  called before JAR building
  -post-jar:                 called after JAR building
  -post-clean:               called after cleaning build products

(Targets beginning with '-' are not intended to be called on their own.)

Example of inserting an obfuscator after compilation could look like this:

    <target name="-post-compile">
        <obfuscate>
            <fileset dir="${build.classes.dir}"/>
        </obfuscate>
    </target>

For list of available properties check the imported 
nbproject/build-impl.xml file. 


Another way to customize the build is by overriding existing main targets.
The targets of interest are: 

  -init-macrodef-javac:     defines macro for javac compilation
  -init-macrodef-junit:     defines macro for junit execution
  -init-macrodef-debug:     defines macro for class debugging
  -init-macrodef-java:      defines macro for class execution
  -do-jar:                  JAR building
  run:                      execution of project 
  -javadoc-build:           Javadoc generation
  test-report:              JUnit report generation

An example of overriding the target for project execution could look like this:

    <target name="run" depends="LED-impl.jar">
        <exec dir="bin" executable="launcher.exe">
            <arg file="${dist.jar}"/>
        </exec>
    </target>

Notice that the overridden target depends on the jar target and not only on 
the compile target as the regular run target does. Again, for a list of available 
properties which you can use, check the target you are overriding in the
nbproject/build-impl.xml file.

我可能會推薦-post-jar

如果您還沒有這樣做，我將成為使用Ant copy任務的農場
