我一直在尝试在我的 Windows 7 机器上克隆和构建一个项目，如下所示：
git clone git@github.com:corvec/project-name.git
cd project-name
git submodule init
git submodule update
ant clean
ant resolve
直到ant resolve按预期工作之前的所有命令，这给了我以下错误消息：

我怀疑这是项目特定配置的问题；我不是这个项目的唯一开发人员，其他开发人员也在工作。更有可能的是，这与我的系统配置有关。他们正在运行 Linux 和 Mac OS，如果这有所作为的话。我想它可能与 git 未跟踪的某些文件有关，但我认为其他开发人员之一会注意到这一点。
我尝试更新文件路径build.properties以使用绝对路径而不是相对路径，如下（基于此建议）：
shared.base=file:///c:/workspace/project-name/core-build
代替
shared.base=core-build
当我这样做时，我收到以下错误消息：

我也尝试过使用新版本的 Ivy，ivy-2.3.0，但我遇到了类似的错误。
我认为这部分是常春藤解决目标：
<target name="resolve" depends="clean-lib, load-ivy" description="--> resolve and retrieve dependencies with ivy">
<echo message="Storing dependencies in lib dir: ${lib.dir}" />
<mkdir dir="lib"/>
<ivy:retrieve />
<ivy:deliver deliverpattern="ivy_delivered.xml" />
</target>
路径
我在下面的 build.properties 和其他相关文件中包含了路径的相关摘录：
// build.xml
<property file="build.properties" />
// build.properties
shared.base=core-build
shared.xml=${shared.base}/xml
// build-ivy-targets.xml (imported into build.xml)
<property name="ivy.settings.dir" value="${shared.xml}/ant/ivy" />
常春藤配置

我发现 Apache Ivy 错误消息意味着它在某个地方无法解析目录，而是将其作为 URL 读取。我应该采取什么步骤来解决这个问题？
