蚂蚁构建失败，没有可见错误 [英] Ant build fails with no visible errors

问题描述

我最终在Eclipse中设置了整个项目，并能够进行构建.我不确定为什么会发生此问题，希望我永远不必找出原因.

我遇到一个问题，我的建筑报告"BUILD FAILED"，但没有报告任何错误.

I'm having a problem where my build is reporting "BUILD FAILED" without reporting any errors.

我正在构建许多旧代码的大型应用程序，现在我可以进行修改了.其他大多数开发人员都使用Eclipse建立了他们的构建，但是我试图通过现有的build.xml文件来构建它.

I'm building a large application of a lot of old code which I now have the joy of modifying. Most of the other developers have set up their builds with Eclipse, but I'm trying to build it through the existing build.xml files.

设置好我的类路径后，构建可以顺利运行，但是在开始编译步骤后不久，它会返回:

After getting my classpath set, the build runs smoothly, but shortly after starting the compile step, it returns:

Lots of "[javac] file.java" lines.

BUILD FAILED
<project path>/build.xml:201: Compile failed; see the compiler error output for details.

这没有帮助.除了堆栈跟踪，build.log没有其他信息:

This is less than helpful. The build.log has no additional information other than the stack trace:

在蚂蚁上添加-debug标志会创建大量信息，而类路径这么长(这么多的jar)，很难对其进行分类.

Adding the -debug flag to ant creates mountains of information, and with such a long classpath (so many jars) it is hard to sort through it.

这是蚂蚁的目标:

  <target name="compile" depends="achmetadata">
    <mkdir dir="${path.build.classes}"/>
    <javac
      listfiles="yes"
      destdir="${path.build.classes}"
      classpathref="project.classpath"
      debug="on"
      deprecation="on"
      fork="yes"
      nowarn="no"
      memoryMaximumSize="512M"
      srcdir="${path.src.java}"
      source="1.4"
      target="1.4"
      >
    -><src path="${path.build.src}"/>
      <patternset refid="production-code"/>
    </javac>
  </target>

classpath是通过该classpathref设置的，并且通过和标签包含了很多jars.

The classpath is set through that classpathref and has a lot of jars included through and tags.

对我应该寻找的东西有什么想法吗?会导致蚂蚁失败的原因是什么?

Any thoughts on what I should be lookinf for? What would cause ant to fail like this?

推荐答案

您可以在调试模式下运行ant构建，以便逐步进行吗?在build.xml中设置一个断点.然后右键单击build.xml并选择Debug As-> Ant Build(假设您正在使用Eclipse).这可以帮助您找出问题所在.

Can you run your ant build in debug mode so that you can step through it? Set a break point in your build.xml. Then Right click on the build.xml and select Debug As -> Ant Build (assuming you are using Eclipse). This might help you to figure out your issue.

HTH.
