当我以详细模式运行ant文件时,出现如下错误。有没有人有任何想法会出错?我是这个新手

因为您的ant文件的名称是build.xml,所以您应该只输入ant而不使用ant build.xml。
即:> ant
[输入]
答案 1 :(得分:10)
答案 2 :(得分:8)
看起来你称之为'ant build..xml'。 ant会自动选择当前目录中的文件build.xml,因此只需调用'ant'(如果定义了default-target)或'ant target'(将调用目标命名目标)。
通过调用'ant -p',您将获得build.xml中定义的目标列表。
编辑:在评论中显示调用'ant -verbose build.xml'。为了正确,这必须被称为'ant -verbose'。将自动使用当前目录中的文件build.xml。如果需要显式指定构建文件(因为它的名称不是build.xml),则必须使用'-f'选项指定构建文件:'ant -verbose -f build.xml'。我希望这会有所帮助。
答案 3 :(得分:3)
在build.xml所在的文件夹中仅运行命令 -
蚁
而不是命令 - “
ant build.xml
`
。如果您使用ant文件作为构建xml,则以下步骤可帮助您执行以下步骤: 打开cmd提示&gt;&gt;切换到项目位置&gt;&gt;键入ant并单击Enter key
答案 4 :(得分:0)
运行ant -d or ant -verbose, but works other times
时,这是 仅 的问题吗?
我注意到了这条错误消息行:
Could not load definitions from resource org/apache/tools/ant/antlib.xml. It could not be found.
org/apache/tools/ant/antlib.xml
文件嵌入在ant.jar
中。 ant
命令实际上是名为ant
的shell脚本或名为ant.bat
的批处理脚本。如果未设置环境变量ANT_HOME,它将通过查看ant
命令本身所在的位置来确定它所在的位置。
有时我会看到有人会移动ant
shell / batch脚本将其放入路径,并且ANT_HOME未设置或设置错误。
你在哪个平台上?这是Windows还是Unix / Linux / MacOS?如果您使用的是Windows,请检查是否设置了%ANT_HOME%。如果是,请确保它是正确的目录。确保已将PATH设置为包含%ANT_HOME%/bin
。
如果您使用的是Unix,请不要将ant shell脚本复制到可执行目录中。相反,建立一个符号链接。我有一个名为/usr/local/bin
的目录,我在其中放置了我想要覆盖/bin
和/usr/bin
中的命令的命令。我的Ant已安装在/opt/ant-1.9.2
中,我有一个从/opt/ant-1.9.2
到/opt/ant
的符号链接。然后,我有/opt/ant/bin
到/usr/local/bin
中所有命令的符号链接。 Ant shell脚本可以检测符号链接并找到正确的Ant HOME位置。
接下来,转到Ant安装目录并查看lib目录以确保ant.jar
存在,并且它包含org/apache/tools/ant/antlib.xml
。您可以使用jar tvf ant.jar
命令。我唯一可以强调的是你确实正确设置了所有东西。您在PATH中有Ant shell脚本,因为您在类路径中包含了Ant的HOME目录的bin目录,或者(如果您在Unix / Linux / MacOS上),您可以象征性地拥有该文件链接到PATH中的目录。
确保您的JAVA_HOME设置正确(在Unix上,您可以使用符号链接技巧让java
命令为您设置),并且您正在使用Java 1.5或更高版本。 Java 1.4将不再适用于较新版本的Ant。
同时运行ant -version
,看看你得到了什么。您可能会遇到与以前相同的错误,这会让我认为您有错误。
让我知道你找到了什么,以及你的操作系统,我可以给你关于重新安装Ant的指示。
答案 5 :(得分:0)
我可能迟到但这对我有用:
<target name="build" />
