Examples with UncheckedIOException org.gradle.api.UncheckedIOException used on opensource projects

Example 81 with UncheckedIOException

use of org.gradle.api.UncheckedIOException in project gradle by gradle.

the class DaemonStartupCommunication method printDaemonStarted.

public void printDaemonStarted(PrintStream target, Long pid, String uid, Address address, File daemonLog) {
    target.print(daemonGreeting());
    // Encode as ascii
    try {
        OutputStream outputStream = new EncodedStream.EncodedOutput(target);
        FlushableEncoder encoder = new OutputStreamBackedEncoder(outputStream);
        encoder.writeNullableString(pid == null ? null : pid.toString());
        encoder.writeString(uid);
        MultiChoiceAddress multiChoiceAddress = (MultiChoiceAddress) address;
        new MultiChoiceAddressSerializer().write(encoder, multiChoiceAddress);
        encoder.writeString(daemonLog.getPath());
        encoder.flush();
    } catch (IOException e) {
        throw new UncheckedIOException(e);
    }
    target.println();
    //ibm vm 1.6 + windows XP gotchas:
    //we need to print something else to the stream after we print the daemon greeting.
    //without it, the parent hangs without receiving the message above (flushing does not help).
    LOGGER.debug("Completed writing the daemon greeting. Closing streams...");
//btw. the ibm vm+winXP also has some issues detecting closed streams by the child but we handle this problem differently.
