github two factor and eclipse

I was talking to a coworker recently about using Eclipse with Git. I had done this back in 2010, but it has been a while. I use git at the command line. He also said Eclipse Oxygen support for Git is better than in the past. Could be. To be honest, I don’t remember doing this in 2010 other than the command line being far easier.

Anyway, I decided to try again. The UI was intuitive. I went to commit. The git staging view (confirmation dialog) showed up at the bottom where the console is rather than popping up like SVN does, but that’s minor. It gave me a choice of “commit and push” which is nice as it isn’t a two step operation.

Then I hit a problem. I turned on GitHub two factor authentication back in 2014. Which means my user id/password isn’t accepted through Eclipse. Luckily this is easy to get past:

  1. Go to github and choose settings (from the upper right pulldown under your avatar)
  2. Click the very last link which is Personal Access Tokens
  3. Choose “Create new token”
  4. Enter a description. I choose “Mac Eclipse”
  5. Choose which permissions you want to grant. I chose the Repo checkbox.

Then I tried to commit and push using my git username and the generated token string as the password. Success. (I didn’t pull because nobody else use this repo)

Note: I got an error “git-receive-pack not permitted” when I didn’t choose the Repo checkbox. In Eclipse, it showed my change as committed (which it was), but it wasn’t pushed.

our oca book as an amazon prime lightning sale

Today was Amazon Prime Day. among other things, they have lightning sales. Our OCA 8 book was one of them.

Up to 100 people could buy a discounted copy of the book. Six people did when I checked shortly before the sale ended. I’m impressed that anyone knew about it. That or 6 people normally buy the book in the 6 hour timespan of the sale and this was random luck.

This screenshot shows our first Amazon Prime Day lightning sale. Very cool.

I read online that some Amazon sales are illusions. So I checked on Camel Camel Camel. In the last three months, the price was never lower than $29 and averaged over $30. So twenty five and change is in fact a sale. Happy Prime Day.

eclipse and line wrapping

Last month, a co-worker referenced an Eclipse setting that I wish I’ve known about for years.  With streams, I typically indent code like:


list.stream().filter(j -> j.disabled)

.map(j -> j.name)

.forEach(System.out::println);

Then I’d let Eclipse format the code and it would turn into a one (or two) line wall of text. I’ve been “solving” that problem by adding comments before some of the methods so Eclipse couldn’t wrap it. Some of those comments are useful for those new to streams. However many are redundant. You probably don’t need a comment that the last line outputs :).

Then my co-worker taught me that there is an Eclipse setting to control the line breaks. Wish this was on by default!

How to configure

If you don’t already have a custom Eclipse formatter:

  1. Eclipse preferences
  2. Java > Code Style > Formatter
  3. New
  4. Enter a name
  5. Click ok

Control line breaks

  1. Edit the profile
  2. Line wrapping tab
  3. Check “Never join already wrapped lines”
