\r command not found. Cygwin script

You might have faced this error when creating a cygwin script, Even a simple script can replicate this issue

#!/bin/sh
date
who
ls
ps ax

./deploy.sh
./deploy.sh: line 2: $'date\r': command not found
./deploy.sh: line 3: $'who\r': command not found

https://cygwin.com/ml/cygwin-announce/2010-08/msg00015.html

This page has the problem in detail.So the solution is

#!/bin/sh
# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
(set -o igncr) 2>/dev/null && set -o igncr; # this comment is needed
date
who
ls
ps ax


This line does the trick. Happy Cygwin scripting :)

Field or property 'jobParameters' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' - Spring Batch

This Error happens when you are trying to retrieve a Job Execution parameter and inject it into a Bean. The bean can be anything a Task let, or a StatmentSetter the error can happen. E.g Implementation <bean id = "flatFileItemReader" scope="step" class="org.springframework.batch.item.file.FlatFileItemReader"> <property name = "resource" value = "#{jobParameters[input.file.name]}" /> </bean> The error is because of the Scope parameter missing Using a scope of  Step  is required in order to use late binding since the bean cannot actually be instantiated until the  Step  starts, which allows the attributes to be found. Because it is not part of the Spring container by default, the scope must be added explicitly. Check out the Documentation here ..  http://docs.spring.io/spring-batch/reference/html/configureStep.html#step-scope

java.security.spec.InvalidKeySpecException: Only RSAPrivate(Crt)KeySpec and PKCS8EncodedKeySpec supported for RSA private keys

public PrivateKey getPrivateKey(String fileName) throws IOException, InvalidKeySpecException, NoSuchAlgorithmException { byte[] keyFileBytes = readKeyFile(fileName); X509EncodedKeySpec spec = new X509EncodedKeySpec(keyFileBytes); KeyFactory kf = KeyFactory.getInstance("RSA"); return kf.generatePrivate(spec); } The reason is this line, This is used to read public key spec and not private key. The private key is read via PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec ( keyBytes ); So as the error says it needs to be in PKCS8 spec format for java to understand.
