Microsoft/Git-Credential-Manager-for-Mac-and-Linux

纠正Mac上的错误：

Fatal: java.lang.Error encountered. Details:
unexpected error
fatal: credential helper '!/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home/bin/java -Ddebug=false -Djava.net.useSystemProxies=true -jar /usr/local/Cellar/git-credential-manager/2.0.3/libexec/git-credential-manager-2.0.3.jar' told us to quit

Mac上的配置需要添加如下 --add-modules java.xml.bind

完整的命令应该是：git config --global --replace-all credential.helper '!java --add-modules java.xml.bind -Ddebug=true -Djava.net.useSystemProxies=true -jar /usr/local/Cellar/git-credential-manager/2.0.3/libexec/git-credential-manager-2.0.3.jar'

我打开了调试模式。如果有其他错误。请留言。

Installation Instructions

This document explains how to obtain the Git Credential Manager for Mac and Linux (GCM4ML) and how to configure Git to use the GCM4ML as its credential helper.

System Requirements

Great care was taken to avoid using any features of Java that would impact compatibility with Java 6. If you find a compatibility issue, please report it and provide as many details about your platform as necessary to reproduce the problem.

Mac OS X version 10.9.5 and up OR a recent GNU/Linux distribution.
Java 6 and up.
Git version 1.9 and up.

How to install

On Mac OS X, installing via Homebrew is highly recommended. On Linux, it is recommended to use Linuxbrew or an RPM-based package manager if you can.

If you can't use any of the package managers, you can also download git-credential-manager-2.0.3.jar somewhere safe and stable, such as ~/git-credential-manager/, and then follow the instructions for automatic or manual configuration.

Installing on Mac using Homebrew or on Linux using Linuxbrew (recommended)

Update the Homebrew/Linuxbrew formulae to make sure you have the latest versions:
```
brew update
```
Install the GCM4ML formula:
```
brew install git-credential-manager
```
Run the GCM4ML in install mode, which will check its requirements and then update the "global" Git configuration file (the one in your home folder):
```
git-credential-manager install
```

Installing on Linux using RPM (recommended)

Download git-credential-manager-2.0.3-1.noarch.rpm and copy the file somewhere locally.
Download the PGP key used to sign the RPM.
Import the signing key into RPM's database:
```
sudo rpm --import RPM-GPG-KEY.txt
```

Verify the GCM4ML RPM:

rpm --checksig --verbose git-credential-manager-2.0.3-1.noarch.rpm

...you should see a line (among those there) that is equal to the following:

V4 RSA/SHA256 Signature, key ID ba34dbc2: OK

Install the RPM:

sudo rpm --install git-credential-manager-2.0.3-1.noarch.rpm

Run the GCM4ML in install mode, which will check its requirements and then update the "global" Git configuration file (the one in your home folder):
```
git-credential-manager install
```

Installing on Mac or Linux without a package manager

Download git-credential-manager-2.0.3.jar somewhere safe and stable, such as ~/git-credential-manager/

Automatic configuration (recommended)

Run the GCM4ML in install mode, which will check its requirements and then update the "global" Git configuration file (the one in your home folder):
```
java -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar install
```

Manual configuration

Configure the credential.helper setting to launch Java with the absolute path to the JAR (make sure you surround the whole value with 'single quotes'):

git config --global credential.helper '!java -Ddebug=false -Djava.net.useSystemProxies=true -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar'

How to enable alternate credential storage

On Linux, the GCM4ML stores credentials in the GNOME Keyring. If GNOME Keyring is unavailable for your Linux distribution, or you are running the GCM4ML via a secure shell (SSH) session, a Git setting can be used to opt into storing credentials unencrypted in a file under your home directory where presumably only you and root have read access.

To enable fallback storage of credentials in this file, run this Git configuration command:

git config --global credential.canFallBackToInsecureStore true

With this setting, the GCM4ML will fallback to storing your credentials in this file:

~/.VSTeamServicesAuthPlugin/insecureStore.xml

How to enable (or disable) debug mode

Debug mode will turn on tracing and assertions, producing a lot of output to stderr. Only turn this on temporarily, when trying to isolate a defect.

Automatic configuration (recommended)

Run the GCM4ML in install mode with the debug property set to true (or false to disable):

java -Ddebug=true -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar install

Manual configuration

Retrieve the value of the credential.helper configuration:

git config --global --get credential.helper git-credential-manager

...it should look like this:

!java -Ddebug=false -Djava.net.useSystemProxies=true -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar

Set a new value for the credential.helper configuration (essentially repeating the manual configuration installation step, being careful with quoting and spaces), changing the value of the debug property to true (or false to disable).

How to configure the proxy server

If your network does not allow a direct connection to remote hosts, you can configure the GCM4ML to perform requests through a web proxy.

Automatic configuration (recommended)

If you are running Gnome 2.x or greater, you can configure the proxy settings using the GUI and the GCM4ML will use those settings thanks to a JVM feature that's activated by setting the java.net.useSystemProxies system property to true (this is now done automatically when running the GCM4ML in install mode).

Manual configuration

If it's not possible to use the automatic proxy server configuration, you must set the appropriate networking properties. Aside from SOCKS proxy servers, which can have their credentials specified through specific properties, authenticated proxy servers are currently not supported.

Retrieve the value of the credential.helper configuration:

git config --global --get credential.helper git-credential-manager

...it should look like this:

!java -Ddebug=false -Djava.net.useSystemProxies=true -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar

Set a new value for the credential.helper configuration (essentially repeating the manual configuration installation step, being careful with quoting and spaces), adding the appropriate properties. For example, if you have a proxy server that can do HTTP and HTTPS, running on the host 192.168.0.117, listening on port 8123, then you would run the following (notice there's a pair of properties for http and one for https).
```
git config --global credential.helper '!java -Ddebug=false -Dhttp.proxyHost=192.168.0.117 -Dhttp.proxyPort=8123 -Dhttps.proxyHost=192.168.0.117 -Dhttps.proxyPort=8123 -jar /home/example/git-credential-manager/git-credential-manager-2.0.3.jar'
```

How to remove or uninstall

We are sad to see you go! Please give us some feedback on how we could do better next time.

Uninstall from Mac using Homebrew or Linux using Linuxbrew

Run the GCM4ML in uninstall mode, which will update the "global" Git configuration file (the one in your home folder):
```
git-credential-manager uninstall
```
Uninstall the git-credential-manager package with Homebrew/Linuxbrew:
```
brew uninstall git-credential-manager
```
Archive the insecureStore.xml file from the git-credential-manager sub-folder under your HOME folder.

Uninstall from Linux using RPM

Run the GCM4ML in uninstall mode, which will update the "global" Git configuration file (the one in your home folder):
```
git-credential-manager uninstall
```

Uninstall the git-credential-manager package with RPM:

sudo rpm --erase git-credential-manager-2.0.3-1.noarch

Archive the insecureStore.xml file from the git-credential-manager sub-folder under your HOME folder.

Automatic configuration removal (recommended)

Retrieve the value of the credential.helper configuration:

git config --global --get credential.helper git-credential-manager
