爪哇蚂蚁，从回购得到常春藤错误

Question

我想一起使用蚂蚁+常春藤。

这是我迄今所做的。我刚刚编辑了ant文件build.xml，以下载ivy jar文件。

<?xml version="1.0"?>

</project> 

这是我的build.properties：在eclipse

# Ant properties for building the springapp 

appserver.home=C:/apache-tomcat-7.0.20 
# for Tomcat 5 use $appserver.home}/server/lib 
# for Tomcat 6 use $appserver.home}/lib 
appserver.lib=C:/apache-tomcat-7.0.20/lib 

deploy.path=C:/apache-tomcat-7.0.20/webapps 

tomcat.manager.url=http://localhost:8080/manager 
tomcat.manager.username=tomcat 
tomcat.manager.password=s3cret 



ivy.install.version=2.2.0 
ivy.jar.file=${lib.build.dir}/ivy-${ivy.install.version}.jar 

当我尝试部署我的war文件和-download-ivy与蚂蚁，我得到以下错误：

Buildfile: C:\Users\Jansu\workspace\HelloWorld\build.xml 
build: 
deploywar: 
-download-ivy: 
    [echo] installing ivy... 
     [get] Getting: http://repo1.maven.org/maven2/org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar

     [get] Error getting http://repo1.maven.org/maven2/org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar to C:\Users\Jansu\workspace\HelloWorld\${lib.build.dir}\ivy-2.2.0.jar 

BUILD FAILED

有什么事情是问题吗？地址http://repo1.maven.org/maven2/org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar存在，我可以从那里手动下载。

根据日志，问题是您的build.properties文件中缺少lib.build.dir定义。因此，为了解决这个问题，你应该：

• 加lib.build.dir定义在build.properties，
• 在-download-ivy目标（<mkdir dir="${lib.build.dir}" />）的开始创建这个目录。
