通过maven-antrun-plugin </if>使用antcontrib <if>任务

标签: java maven ant-contrib maven-antrun-plugin

我的maven java项目使用maven-antrun-plugin来执行部署我的应用程序的deploy.xml ant脚本。 deploy.xml使用<if>任务,这似乎导致了问题;

  

[INFO]执行任务
    [taskdef]无法从资源net / sf / antcontrib / antlib.xml加载定义。它无法找到。

     

部署:
  [INFO] ----------------------------------------------- -------------------------
  [错误]构建错误

  [INFO]发生了Ant BuildException:执行此行时发生以下错误:

  原因:名称未定义   行动:检查拼写   操作:检查是否已声明任何自定义任务/类型   操作:检查是否有任何&lt; presetdef&gt; /&lt; macrodef&gt;声明已经发生。

这是我的pom的antrun插件配置;

                        <ant antfile="${basedir}/deploy.xml">
                            <target name="deploy" />
                        </ant>
                </tasks>
            </configuration>
            <goals>

            <version>1.7.1</version>
        </dependency>
    </dependencies>
</plugin>

..这里是我的deploy.xml的相关部分;

<target name="deploy" if="deploy">
    <if>    <!-- line 24 -->
        <and>

为什么我看看我的maven回购我可以看到ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar当我看到罐子里面时我可以看到net/sf/antcontrib/antcontrib.properties所以没问题。

当我检查maven.compile.classpathmaven.compile.classpathmaven.compile.classpath的值时,我看不到对antcontrib的任何引用,这可能是问题吗?当antcontrib被定义为依赖时,为什么它们不出现?

我认为在编译类路径中添加ant以运行maven插件并不是一个好主意。

我使用Maven 3.0.4,它通过为ant-contrib标记指定名称空间来工作,例如:

<configuration>
  <target>
    <echo message="The first five letters of the alphabet are:"/>
    <ac:for list="a,b,c,d,e" param="letter" xmlns:ac="antlib:net.sf.antcontrib">
      <sequential>
        <echo>Letter @{letter}</echo>
      </sequential>
    </ac:for>
  </target>
</configuration>

我的maven-antrun-plugin个依赖关系:

<dependencies>
  <dependency>
    <groupId>ant-contrib</groupId>
    <artifactId>ant-contrib</artifactId>
    <version>1.0b3</version>
    <exclusions>
      <exclusion>
        <groupId>ant</groupId>
        <artifactId>ant</artifactId>
      </exclusion>
    </exclusions>
  </dependency>
  <dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant-nodeps</artifactId>
    <version>1.8.1</version>
  </dependency>
</dependencies>

好的,我已经解决了。

将依赖项移出<build><plugin>标记并将其与其他项目依赖项放在一起似乎已经成功了。

答案 2 :(得分:3)

我发现你需要在插件中包含ant-contrib依赖项,这将使taskdef标记能够找到antcontrib.properties

另一种解决方案是:将ant-contrib-1.0b3.jar保存到路径中然后像这样定义

<property name="runningLocation" location="" />
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
    <classpath>
        <pathelement location="${runningLocation}/ant-contrib-1.0b3.jar" />
    </classpath>
</taskdef>

然后

<target name="doSomething">
    <if>
        <equals arg1="${someProp}" arg2="YES" />
        <then>
            <echo message="It is YES" />
        </then>
        <else>
            <echo message="It is not YES" />
        </else>
    </if>
</target>
