Ant目标失败：Antlib还是Ivy问题？ [英] Ant target failing: Antlib or Ivy issue?
问题描述
可能重复：
Ivy无法解决依赖性，无法找到原因
我正在尝试运行以下构建任务（ initIvy ）：
I'm trying to run the following build task (initIvy):
<?xml version="1.0" encoding="UTF-8"?>
<project name="myproject-build" default="package" basedir=".." xmlns:ivy="antlib:org.apache.ivy.ant">
<property file="build/build.properties"/>
<property environment="env"/>
<!-- Ant library path, including all of its plugins. -->
<path id="ant.lib.path">
<fileset dir="${env.ANT_HOME}/lib" includes="*.jar"/>
</path>
<!-- CONFIGURE IVY -->
<taskdef resource="org/apache/ivy/ant/antlib.xml"
uri="antlib:org.apache.ivy.ant" classpathref="ant.lib.path"/>
<!-- Use Ivy tasks to resolve dependencies into the local Ivy cache. -->
<target name="initIvy">
<!-- Initialize Ivy and connect to host repository. -->
<echo message="Initializing Apache Ivy and connecting to the host repository."/>
<ivy:settings url="${ivy.std.repo.settings.url}" realm="${ivy.std.repo.realm}" username="${ivy.std.repo.username}" passwd="${ivy.std.repo.password}"/>
<!-- Clear/flush the Ivy cache. -->
<echo message="Cleaning the local Ivy cache for the current build."/>
<ivy:cleancache/>
</target>
<!-- Rest of buildfile omitted for brevity. -->
</project>
当我运行 ant -buildfile build.xml initIvy 我得到以下输出：
When I run ant -buildfile build.xml initIvy I get the following output:
Buildfile: /<path-to-my-project>/build/build.xml
[taskdef] Could not load definitions from resource org/apache/ivy/ant/antlib.xml. It could not be found.
initIvy:
[echo] Initializing Apache Ivy and connecting to the host repository.
BUILD FAILED
/<path-to-my-project>/build/build.xml:81: Problem: failed to create task or type antlib:org.apache.ivy.ant:settings
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-/<path-to-my-ANT_HOME>/lib
-/home/myUser/.ant/lib
-a directory added on the command line with the -lib argument
当我转到$ { ANT_HOME} / lib，我没有看到任何标记为antlib * .jar的JAR。
When I go to ${ANT_HOME}/lib, I don't see any JARs labeled "antlib*.jar".
所以我猜测我下载了一个不包含Antlib的Ant版本，现在我正在使用Ivy（使用Antlib），构建是否会窒息？
So I'm guessing I downloaded a version of Ant that did not include Antlib, and now that I'm using Ivy (which uses Antlib), the build is choking?
如果这是一个Antlib问题，那么我相信我想要一个可用的发行版这里。如果是这样，有人可以确认我应该使用哪一个（只包含Antlib而不是其他任何东西），并确认安装它的过程;即，是否就像在$ {ANT_HOME} / lib中放入正确的JAR一样简单？等等。
If this is an Antlib issue, then I believe I want one of the distros available here. If so, can someone confirm which one I should use (that only contains Antlib and not anything else), and confirm the process for installing it; i.e., is it just as simple as putting the correct JAR in ${ANT_HOME}/lib? Etc.
如果这是一个常春藤问题，那么有人能指出我正确的方向吗？
If this is an Ivy issue, then can someone point me in the right direction as to what could be going on?
如果这既不是Antlib也不是常春藤，对于上面的问题同样如此。提前致谢！
And if this is neither Antlib nor Ivy, ditto for the question directly above. Thanks in advance!
推荐答案
我认为您可能缺少Apache IVY库。从这里下载 - apache ivy 将jar复制到ant lib目录中。
I think you might be missing Apache IVY library. Download it from here - apache ivy Copy the jar in your ant lib directory.
例如（根据需要更改版本号）：
For example (change version numbers as appropriate):
- 下载并安装Ant（例如，
C：\ Apps\Tools \apache-ant-1.9.7）。 - 下载并提取常春藤（例如，
C：\ Users \UserName \Downloads\apache-ivy-2.4.0） - 复制
\ Users \UserName \Downloads \apache-ivy-2.4.0 \ivy-2.4.0.jarintoC：\ Apps\Tools\apache-ant-1.9.7 \lib。
- Download and install Ant (e.g.,
C:\Apps\Tools\apache-ant-1.9.7). - Download and extract Ivy (e.g.,
C:\Users\UserName\Downloads\apache-ivy-2.4.0) - Copy
C:\Users\UserName\Downloads\apache-ivy-2.4.0\ivy-2.4.0.jarintoC:\Apps\Tools\apache-ant-1.9.7\lib.
配置Ant使用常春藤。
Ant is configured to use Ivy.
