三、创建account.json

创建account.json文件内容如下：

[
  {
    "$id": "1",
    "$type": "SourceTree.Api.Host.Identity.Model.IdentityAccount, SourceTree.Api.Host.Identity",
    "Authenticate": true,
    "HostInstance": {
      "$id": "2",
      "$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountInstance, SourceTree.Host.AtlassianAccount",
      "Host": {
        "$id": "3",
        "$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountHost, SourceTree.Host.AtlassianAccount",
        "Id": "atlassian account"
      },
      "BaseUrl": "https://id.atlassian.com/"
    },
    "Credentials": {
      "$id": "4",
      "$type": "SourceTree.Model.BasicAuthCredentials, SourceTree.Api.Account",
      "Username": "",
      "Email": null
    },
    "IsDefault": false
  }
]

四、修改user.config

路径：C:\Users${currentUser}\Appdata\Local\Atlassian\SourceTree.exe_Url_yjhzxxhcu2ommegrdorjf3q1oqllqxiq\3.3.8.3848
在user.config中添加如下语句：

<setting name="AgreedToEULA" serializeAs="String">
    <value>True</value>
</setting>
<setting name="AgreedToEULAVersion" serializeAs="String">
    <value>20160201</value>
</setting>
