DO NOT REPLY [Bug 51161] New: Stream Closed error in
DefaultInputHandler with embedded ant task
https://issues.apache.org/bugzilla/show_bug.cgi?id=51161
Bug #: 51161
Summary: Stream Closed error in DefaultInputHandler with
embedded ant <input> task
Product: Ant
Version: 1.8.1
Platform: Macintosh
Status: NEW
Severity: normal
Priority: P2
Component: Core
AssignedTo: notifications@ant.apache.org
ReportedBy: kldavis4@gmail.com
Classification: Unclassified
I am using the maven-antrun-plugin 1.6 with the <input> task and the default
input handler. When I enter input, it throws a BuildException, "Failed to read
input from Console". The root exception is:
java.io.IOException: Stream closed
at
java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:145)
at java.io.BufferedInputStream.read(BufferedInputStream.java:308)
at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:264)
at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306)
at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158)
at java.io.InputStreamReader.read(InputStreamReader.java:167)
at java.io.BufferedReader.fill(BufferedReader.java:136)
at java.io.BufferedReader.readLine(BufferedReader.java:299)
at java.io.BufferedReader.readLine(BufferedReader.java:362)
I was able to fix this issue by wrapping the input stream in
KeepAliveInputStream as follows:
public void handleInput(InputRequest request) throws BuildException {
String prompt = getPrompt(request);
BufferedReader r = null;
try {
r = new BufferedReader(new InputStreamReader(new
KeepAliveInputStream(getInputStream())));
do {
System.err.print(prompt + ": ");
System.err.flush();
try {
String input = r.readLine();
request.setInput(input);
} catch (IOException e) {
throw new BuildException("Failed to read input from"
+ " Console.", e);
}
} while (!request.isInputValid());
} finally {
if (r != null) {
try {
r.close();
} catch (IOException e) {
throw new BuildException("Failed to close input.", e);
}
}
}
}

Ok, sorry about that. If you run 'mvn generate-sources' it doesn't run the ant
plugin. Please run it with 'mvn compile'. That should trigger the problem.

Sorry for the late follow up, but I cannot reproduce the error. I tried with
both maven 2 and maven 3. Here is what I got:
