cp with force overwrite

I was recently trying to copy a directory over an existing one and kept getting prompted - asking if I wanted to overwrite existing files - even though I was using the force option:
cp -Rf dir1 dir2
I found the answer here - it was caused by an alias forcing the interactive mode.

Quick solution is to bypass the alias by an absolute reference to cp:
/bin/cp -Rf dir1 dir2

AspectJWeaver with JDK 7 - error - only supported at Java 5 compliance level or above

I came across this problem with an older project - when I switched from jdk6 to jdk7, when the application started I encountered: nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException:   error annotation type patterns are only supported at Java 5 compliance level or above I didn't want a purely maven solution because during development I run the app in Tomcat via the IDE (Intellij IDEA).

JUnit parameterized test with Spring autowiring AND transactions

I've been writing JUnit Parameterized tests (a nice intro here - also see Theories ) to do some data driven API testing. Now, when introducing Spring into the mix there are a couple of extra things to do . I came unstuck though because I was trying to do Transactional tests - since I'm now using @RunWith(Parameterized.class) and setting up my Spring TestContextManager manually the @Transaction annotations caused an exception: java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments were given I couldn't find any built in solution, so I've gone with manual transaction management in my test, using doInTransaction: @RunWith(Parameterized.class) @ContextConfiguration(locations = "classpath*:/testContext.xml") public class MyTest { @Autowired PlatformTransactionManager transactionManager; private TestContextManager testContextManager; public MyTest (... parameters for test) { // store parameters in instance v...

Intellij tip - Joining multiple lines into one

There are times when you have some code with each statement on its own line, and you want to move it all onto one line. CSS is where I've needed this the most. You start off with some code like this: And really want this: Intellij has a very simple way to do this by using Ctrl-Shift-J - for more information, see http://www.jetbrains.com/idea/webhelp/joining-lines-and-literals.html
