NG构建在使用Ant Build构建Angular5项目时不起作用

Question

我有一个Java应用程序，该应用程序在Localhost：9080和另一个Angular5 Project(AngularWeb(上运行，而在同一项目的WebContent文件夹中运行，该文件夹在其他端口Local -Host上运行：4200

根据要求，我需要集成两个项目以在Localhost上的同一服务服务器上运行：9080和(Java和Angular Projects(都需要位于同一位置，这就是为什么我在Web内容文件夹中拥有Angular Project的原因。

请帮助我了解缺少的东西。

首先：我在Angular项目中创建了一个proxy.conf.json文件，以定位Localhost：9080。

第二：我已经更改了包装。" start"：" ng serve -proxy-conf proxy.conf.json"，

第三：我在build.xml文件中添加了一些目标

...
<property name="project.angularWebPath" location="${project.webContentPathh}/angularweb" />
<target name="mkfolders">
    <mkdir dir="${project.webContentPath}/js" />
    <mkdir dir="${project.webContentPath}/css" />
    <mkdir dir="${project.webContentPath}/img" />
    <mkdir dir="${project.webContentPath}/lib" />
    <mkdir dir="${project.webContentPath}/partials" />
</target>
<target name="mkfiles">
    <touch file="${project.webContentPath}/js/app.js" />
    <touch file="${project.webContentPath}/js/controller.js" />
    <touch file="${project.webContentPath}/js/directives.js" />
    <touch file="${project.webContentPath}/js/filters.js" />
    <touch file="${project.webContentPath}/js/services.js" />
    <touch file="${project.webContentPath}/index.html" />
</target>
<target name="ngBuild">
    <echo>Building Angular Project</echo>
    <exec executable="${project.angularWebPath}/node_modules/@angular/cli/bin/ng.cmd" failonerror="true">
        <arg value="build" />
        <arg value="--prod" />
        <arg value="--bh" />
    </exec>
    <echo>Built Angular Project</echo>
</target>
<target name="angularBuild">
    <antcall target="mkfolders" />
    <antcall target="mkfiles" />
    <!--<antcall target="npmInstall" />-->
    <antcall target="ngBuild" />
</target>
...
...

现在，当我在ANT中运行AngularBuild时，它会产生以下错误

Buildfile: D:devopsrepositorykomponente_serverRechercheEARbuild.xml
  [clover-env] Loading clover.xml: jar:file:/D:/devops/repository/komponente_server/Shared/testlib/clover.jar!/clover.xml

ant的exec任务直接在Windows中启动文件。尝试将executable属性设置为仅cmd本身，然后将文件作为参数传递。官方文档页面更详细地介绍了为什么是这样的：https：//ant.apache.org/manual/tasks/exec.html

另外，通常是通过目标依赖性构建构建而不是使用antcall任务的顺序列表。

的一个好主意。
