无法启动从命令行自由简介：无法创建任务或键入的antlib：com.ibm.websphere.wlp.ant：服务器

Question

我试图启动WebSphere Liberty配置文件服务器（称为WL_UAT_Server）

<project basedir="." default="help" name="myProject" xmlns:wlp="antlib:com.ibm.websphere.wlp.ant"> 
     <target name="liberty-start"> 
     <wlp:server id="test" installDir="/opt/IBM/WebSphere/Liberty" operation="start" serverName="WL_UAT_Server"/> 
     </target> 
</project> 

从以下命令：

ant -f /opt/myProject/build.xml "liberty-start" 

，但系统是给以下错误：

/opt/myProject/build.xml:144: Problem: failed to create task or type antlib:com.ibm.websphere.wlp.ant:server 
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: 
     -/usr/share/ant/lib 
     -/home/root/.ant/lib 
     -a directory added on the command line with the -lib argument

我测试过上的蚂蚁1.7.1下面的生成文件它工作正常。 我收到你的错误，如果我从ant\lib文件夹中删除wlp-anttasks.jar。 那么仔细检查一下，如果文件存在并且可读 - 正确的权限？也许你正在从不同的用户运行构建？或者，您可能无法访问Liberty或服务器文件夹？

检查，如果同一用户可以通过命令行使用启动服务器：

C:\IBM\WebSphere\wlp\bin>server start WLP_UAT_Server 
Starting server WLP_UAT_Server. 
Server WLP_UAT_Server started. 

这是我build.xml文件

<project name="libertyTest" default="start-server" xmlns:wlp="antlib:com.ibm.websphere.wlp.ant"> 
    <description> 
      description 
    </description> 
    <!-- set global properties for this build --> 
     <property name="wlp_install_dir" value="C:/IBM/WebSphere/wlp"/> 
     <property name="serverName" value="WLP_UAT_Server"/> 

    <target name="start-server" description="description"> 
     <wlp:server id="wlp.ant.test" installDir="${wlp_install_dir}" operation="start" serverName="${serverName}" /> 
     <wlp:server ref="wlp.ant.test" operation="status"/> 
    </target> 

    <target name="stop-server" description="description"> 
      <wlp:server id="wlp.ant.test" installDir="${wlp_install_dir}" operation="stop" serverName="${serverName}" /> 
    </target> 
</project> 

从诊断Ant属性：

------------------------------------------- 
ANT PROPERTIES

ant.version: Apache Ant version 1.7.1 compiled on June 27 2008 
ant.java.version: 1.6

ant.home: C:\install\apache-ant-1.7.1\bin\..

看起来您已经错过了将wlp-anttasks.jar复制到您的$ANT_HOME/lib目录中的步骤。另外，如果你不想改变你的Ant安装，您可以使用 的typedef任务加载自由任务，例如：

<typedef resource="net/wasdev/wlp/ant/antlib.xml" 
     uri="antlib:net.wasdev.wlp.ant" 
     classpath="somewhere/wlp-anttasks.jar"/>
