Apache Ivy 简明教程
Apache IVY - Info Task
info 任务用于在文件中设置 ivy 专有信息,且无需进行任何依赖项解析就可使用。
让我们按照 IVY - Resolve Task 章节中的描述创建 Tester.java、build.xml 和 ivy.xml。
更新 build.xml 以使用 ivy 发布任务。我们首先将创建 jar 文件,然后发布它。在发布任务之前,我们已使用 info 任务设置了所需的 ivy 信息。
build.xml
<project name="test" default="resolve" xmlns:ivy="antlib:org.apache.ivy.ant">
<property name = "build.dir" value = "build"/>
<target name="resolve" description="resolve dependencies">
<ivy:resolve />
</target>
<target name = "jar">
<jar destfile = "${build.dir}/lib/application.jar"
basedir = "${build.dir}/classes">
<manifest>
<attribute name = "Main-Class" value = "com.tutorialspoint.Application"/>
</manifest>
</jar>
</target>
<target name="publish" depends="jar">
<ivy:info file="ivy.xml" />
<ivy:publish resolver="local" pubrevision="1.0" overwrite="true">
<artifacts pattern="${build.dir}/lib/[artifact].[ext]" />
</ivy:publish>
</target>
</project>
此处发布任务首先构建 jar 文件,然后使用 ivy:info 任务设置信息,然后将工件发布到本地仓库。
Building the project
因为我们已准备好所有文件。只需转到控制台。导航至 E:\ivy 文件夹并运行 ant 命令。
E:\ivy > ant publish
Ivy 将执行操作,解析依赖关系,您将看到以下结果。
Buildfile: E:\ivy\build.xml
jar:
publish:
[ivy:info] :: Apache Ivy 2.5.0 - 20191020104435 :: https://ant.apache.org/ivy/
::
[ivy:info] :: loading settings :: url = jar:file:/E:/Apache/apache-ant-1.9.14/l
ib/ivy-2.5.0.jar!/org/apache/ivy/core/settings/ivysettings.xml
[ivy:publish] :: publishing :: com.tutorialspoint#test
[ivy:publish] published application to C:\Users\Acer\.ivy2\local\com.tutorials
point\test\1.0\jars\application.jar
[ivy:publish] published ivy to C:\Users\Acer\.ivy2\local\com.tutorialspoint\te
st\1.0\ivys\ivy.xml
BUILD SUCCESSFUL
Total time: 0 seconds
如果我们不设置 info 任务,则发布任务将不起作用。使用下面修改后的 build.xml,并查看缺少组织属性等错误。
build.xml
<project name="test" default="resolve" xmlns:ivy="antlib:org.apache.ivy.ant">
<property name = "build.dir" value = "build"/>
<target name="resolve" description="resolve dependencies">
<ivy:resolve />
</target>
<target name = "jar">
<jar destfile = "${build.dir}/lib/application.jar"
basedir = "${build.dir}/classes">
<manifest>
<attribute name = "Main-Class" value = "com.tutorialspoint.Application"/>
</manifest>
</jar>
</target>
<target name="publish" depends="jar">
<ivy:publish resolver="local" pubrevision="1.0" overwrite="true">
<artifacts pattern="${build.dir}/lib/[artifact].[ext]" />
</ivy:publish>
</target>
</project>
导航到 *E: > ivy * 文件夹并运行 ant 命令。
E:\ivy > ant publish
Ivy 将执行操作,解析依赖关系,您将看到以下结果。
