我已经在Linux环境中安装了Jenkins。我有一台充当从机的SunOs服务器，该服务器上有phpunit.phar二进制文件。在服务器中，我可以执行phpunit。我创建了一个Jenkins作业，该作业将在从机上运行，该从机将使用ANt构建执行phpunit。
build.xml：
<project name="name-of-project" default="full-build">
<!-- By default, we assume all tools to be on the $PATH -->
<property name="phpunit" value="phpunit"/>
<!--
<property name="phpunit" value="${basedir}/build/tools/phpunit.phar"/>
-->
<!--
Use this when the tools are managed by Composer in ${basedir}/vendor/bin
<property name="phpunit" value="${basedir}/vendor/bin/phpunit"/>
-->
<target name="full-build" depends="prepare,lint,phpunit,-check-failure" description="Performs static analysis, runs the tests, and generates project documentation"/>
<!--
Adjust the threadCount attribute's value to the number of CPUs
-->
<target name="clean" unless="clean.done" description="Cleanup build artifacts">
<delete dir="${basedir}/build/api"/>
<delete dir="${basedir}/build/coverage"/>

</target>

</not>
</condition>
</fail>
</target>
</project>
当我触发Jenkins作业时，我的ANT作业失败，并显示以下错误消息：
执行失败：java.io.IOException：无法运行程序“ phpunit”（在 目录“ / home / jenkins / workspace”）：错误= 2，没有此类文件或 目录
我也尝试通过在build.xml中提供phpunit路径，然后得到一条错误消息：
[phpunit] / usr / bin / env：没有这样的文件或目录
如何解决此问题？
