How to fix ssh-add -K issue with Mac OS Sierra?


Before Mac OS Sierra, using this line of code save your time adding ssh keys once in your keychain:

ssh-add -K ~/.ssh/{your key}

but recently there is some issue with Mac OS new version and all your keys added to keychain reset on startup.

to fix this issue I found a solution with might be helpful.

  1. create a bash file containing these codes (~/.ssh/
count=`ssh-add -l |grep -v "The agent" |wc -l|awk '{print $1}'`
 if [ "0" == "${count}" ]
 arr=`cd ~/.ssh && find id_rsa* -not -path '*.pub'`
 for key in ${arr[@]}
 ssh-add -k ~/.ssh/${key}
  1. make this file executable:
chmod +x ~/.ssh/
  1. add this file to your Mac launch (~/Library/LaunchAgents/ssh_fixer.plist):
<plist version="1.0">
 <string>/Users/{YOUR USERNAME}/.ssh/</string>
  1. now restart your Mac!


That’s it! 😎

> Building 10%When running gradle with java 8, you must set the path to the old jdk, either with property retrolambda.oldJdk or environment variable JAVA5_HOME/JAVA6_HOME/JAVA7_HOME

The problem is you have to configure environment variables for Java_Home, Java7_Home, Java6_Home and etc in circleci virtual machine.

this circle.yml file could help you in this regard:

stetho-timber Library issue with new Timber 4.1.2


While I was trying to use stetho-timber Library in my Android application I faced this problem:

Error:Module 'com.facebook.stetho:stetho-timber:1.3.1' depends on one or more Android Libraries but is a jar

After inspecting in its codes I found that it uses timber v3.0.1!

Just add this to your build.gradle dependencies tag to exclude timber within the stetho library,
cause it is an old version and conflicts with new one:

dependencies {
    compile ("com.facebook.stetho:stetho-timber:1.3.1") {
        exclude group: "com.jakewharton.timber", module: "timber"

I have recently found Facebook Stetho Library and using it is fantastic, give it a try! :)
