我正在尝试在我的ant脚本中创建trycatch块。我收到这个错误：

我尝试按照try catch的例子，但没有一个工作。 http://ant-contrib.sourceforge.net/tasks/tasks/trycatch.html
我收到此错误在所有情况下都没有定义同名。我不知道我是否将这个块嵌套在正确的位置，因为我试图将它放在特定的构建阶段。
如何让这个trycatch工作？

我仍然遇到同样的错误

答案 0 :(得分：0)
trycatch是ant-contrib的一部分。因此，您需要在此库中声明插件的依赖项，并在执行配置中的任务之前声明其中包含的任务：
<execution>
<id>test-compile</id>
<phase>test-compile</phase>
<configuration>
<tasks>
<!-- declare ant-contrib tasks -->
<taskdef resource="net/sf/antcontrib/antlib.xml" />
<echo message="***** Hello from test-compile phase! *****" />
<trycatch>
<try>
<replaceregexp match="\s+" replace=" " flags="g" byline="true">
<fileset dir="${basedir}/target/ROOT/WEB-INF/views/" includes="**/*.jsp"></fileset>
</replaceregexp>
<replaceregexp match="<!--.*build.*-->" replace=" " flags="g" byline="true">
<fileset dir="${basedir}/target/ROOT/WEB-INF/views/" includes="**/*.jsp"></fileset>
</replaceregexp>
</try>
</trycatch>
</tasks>
</configuration>
