Java Ant JUnit任务因ClosedByInterruptException失败

我的JUnit测试由于一个ClosedByInterruptException而失败，在运行完一个测试后，它无法编写它的测试报告，只是由于以下异常而停止：

我使用的是ant-junit-1.10.5-jar。方法endTestSuite的代码段是：

        if (out != null) {
            Writer wri = null;
            try {
                wri = new BufferedWriter(new OutputStreamWriter(out, "UTF8"));
                wri.write("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n");
                new DOMElementWriter().write(rootElement, wri, 0, "  ");
            } catch (final IOException exc) {
                throw new BuildException("Unable to write log file", exc);
            }

if（out！=null）{
Writer wri=null；
试一试{
wri=新的缓冲写入程序（新的OutputStreamWriter（输出，“UTF8”））；
写入（“\n”）；
new DOMElementWriter（）.write（rootElement，wri，0，“”）；
}捕获（最终IOException exc）{
抛出新的BuildException（“无法写入日志文件”，exc）；
}

我的JUnit ant目标如下所示：

    <junit dir="${test.path}/${test.dir}" fork="on" forkmode="once" haltonfailure="${junit.halt.on.failure}" outputtoformatters="true" printsummary="on" showoutput="true">

不确定它是否能帮助您，但它仍然应该让您知道为什么会发生异常，然后您可能会找到一条好的路径……只是一次尝试。。。
