未能创建任务或键入antlib:com.ibm.websphere.wlp.ant:server

Question

以下是WebSphere Liberty Profile的服务器配置：

product = WebSphere Application Server 8.5.5.1
wlp.install.dir = /opt/IBM/WebSphere/Liberty/
java.home = /root/Downloads/jre1.6.0_45
java.version = 1.6.0_45
java.runtime = Java(TM) SE Runtime Environment (1.6.0_45-b06)
os = Linux (2.6.32-431.23.3.el6.x86_64; amd64) (en_US)

我已经将"wlp-anttasks.jar"复制到"/opt/worklight/eclipse/plugins/org.apache.ant_1.8.4.v201303080030/lib"位置，并运行以下ant任务来启动Liberty服务器：

<project basedir="." xmlns:wlp="antlib:com.ibm.websphere.wlp.ant">
    <property name="wl.server.home" value="/opt/IBM/WebSphere/Liberty"/>
    <property name="wl.server.name" value="WL_UAT_Server"/>
    <target name="test">
      <wlp:server id="test" installDir="${wl.server.home}" operation="start" serverName="${wl.server.name}"/>
    </target>
</project>

执行后，它给我以下错误：

BUILD FAILED
/opt/UIWS/UI/Liberty.xml:6: Problem: failed to create task or type antlib:com.ibm.websphere.wlp.ant:server
Cause: The name is undefined.
Action: Check the spelling.

This appears to be an antlib declaration.

        -a directory added on the command line with the -lib argument

如果您直接从Eclipse开始构建，我相信它不会自动从eclipse/plugins/org.apache.ant_1.8.4.v201303080030/lib文件夹添加所有jar。最好手动提供。

• 如果要为工作区中的所有构建文件启用任务，请通过Window > Preferences > Ant > Runtime修改工作区属性，并将wlp-anttasks.jar作为外部jar添加到Ant Home Entries
• 如果您只想为单个构建文件启用它，请选择build.xml，右键单击Run As > Ant build ...，然后切换到Classpath选项卡，并将wlp-anttasks.jar作为外部jar添加到User entries

无论在哪种情况下，您的构建都将成功。
