NAnt：检查包含文件是否已包含

Question

有人知道检查文件是否已包含的方法吗？

<include buildfile="${script.dir}\util.include.nant" />
.
.
.
.
<include buildfile="${script.dir}\util.include.nant" />

这将引发目标重复的异常。有办法解决吗？

提前致谢

Answer 1

刚刚看到这个问题，它似乎相关，并决定更改其中一个重复项的大小写a.build 在我的另一个答案中：

<include buildfile="c.build" />
<include buildfile="C.build" />

Boom - 重复目标错误。看起来 nant 足够聪明，可以忽略重复的包含，但在比较它们时区分大小写。

Answer 2

这个最小的例子在 nant 0.86.3075.0 中对我来说工作正常：

在这个例子中，a.build 和 b.build 都包含 c.build 多次。 a.build 和 b.build 也相互包含，但不依赖于彼此的目标，因为这会产生循环依赖。

请注意在项目级别使用 echo - 这些似乎是在包含文件时出现的，这可能会帮助您调试问题。

a.build:

<?xml version="1.0" encoding="utf-8"?>
<project default="a.go" name="a">

    <echo message="In A"/>

    <include buildfile="b.build" />
    <include buildfile="b.build" />
    <include buildfile="c.build" />
    <include buildfile="c.build" />

    <target name="a.go" depends="c.go">
        <echo message="Building A"/>
    </target>

    <include buildfile="b.build" />
    <include buildfile="c.build" />

</project>

b.build:

<?xml version="1.0" encoding="utf-8"?>
<project default="b.go" name="b">

    <echo message="In B"/>

    <include buildfile="a.build" />
    <include buildfile="a.build" />
    <include buildfile="c.build" />
    <include buildfile="c.build" />

    <target name="b.go" depends="c.go">
        <echo message="Building B"/>
    </target>

    <include buildfile="a.build" />
    <include buildfile="c.build" />

</project>

c.build:

<?xml version="1.0" encoding="utf-8"?>
<project default="c.go" name="c">

    <echo message="In C"/>

    <target name="c.go">
        <echo message="Building C"/>
    </target>

</project>
