java - 在 Java 中编译/构建项目时将 jar 复制到输出文件夹

Question

快速提问：在 Java 中编译/构建项目时，如何配置NetBeans复制 jar 文件（我正在sqlite.jar用于我的应用程序） ？output folder

Answer 1

使用 Ant 构建。比使用 ide 制作 jar 更好

Answer 2

在 NetBeans 中，切换到“文件”选项卡。扩展您的项目（要构建的项目）。

双击build.xml.

您可以覆盖许多构建目标......build.xml它们的文档，但这里是转储

<!--

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.

我可能会推荐-post-jar

如果你还没有这样做，我会很熟悉Antcopy任务
