可能重复:常 Spring 藤无法解决依赖,无法找到原因
我正在尝试运行以下构建任务( 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="${ivy.std.repo.password}"/>
<!-- Clear/flush the Ivy cache. -->
<echo message="Cleaning the local Ivy cache for the current build."/>
<ivy:cleancache/>
</target>
<!-- Rest of buildfile omitted for brevity. -->
</project>
当我运行 ant -buildfile build.xml initIvy
时,我得到以下输出:
Buildfile: /<path-to-my-project>/build/build.xml
[taskdef] Could not load definitions from resource org/apache/ivy/ant/antlib.xml. It could not be found.
initIvy:
[echo] Initializing Apache Ivy and connecting to the host repository.
BUILD FAILED
/<path-to-my-project>/build/build.xml:81: Problem: failed to create task or type antlib:org.apache.ivy.ant:settings
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-/<path-to-my-ANT_HOME>/lib
-/home/myUser/.ant/lib
-a directory added on the command line with the -lib argument
当我转到$ / lib时,我没有看到任何标记为“antlib * .jar”的JAR .
所以我猜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?
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here . 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$ / lib中放入正确的JAR一样简单?等等 .
如果这是一个常 Spring 藤问题,那么有人可以指出我正确的方向可能会发生什么?
如果这既不是Antlib也不是常 Spring 藤,对于上面的问题同样如此 . 提前致谢!

我想你可能会遗漏Apache IVY库 . 从这里下载 - apache ivy复制ant lib目录中的jar .
例如(根据需要更改版本号):
下载并安装Ant(例如,
C:\Apps\Tools\apache-ant-1.9.7
) .下载并提取常 Spring 藤(例如,
C:\Users\UserName\Downloads\apache-ivy-2.4.0
)将
C:\Users\UserName\Downloads\apache-ivy-2.4.0\ivy-2.4.0.jar
复制到C:\Apps\Tools\apache-ant-1.9.7\lib
.Ant配置为使用Ivy .
