-      "readme": "Template for Salesforce to MySQL using Ballerina\n\n# Salesforce to MySQL using Ballerina \n\nThis is a template for [Salesforce to MySQL Database tutorial](https:\/\/ei.docs.wso2.com\/en\/latest\/ballerina-integrator\/learn\/tutorials\/saas-integrations\/sfdc46\/salesforce-to-mysql-db\/1\/). Please refer to it for more details on what you are going to build here. This template provides a starting point for your scenario. \n\n## Using the Template\n\nRun the following command to pull the `salesforce_to_mysql` template from Ballerina Central.\n\n```\n$ bal pull wso2\/salesforce_to_mysql\n```\n\nCreate a new project.\n\n```bash\n$ bal new salesforce-to-mysql-db\n```\n\nNow navigate into the above project directory you created and run the following command to apply the predefined template \nyou pulled earlier.\n\n```bash\n$ bal add salesforce_to_mysql -t wso2\/salesforce_to_mysql\n```\n\nThis automatically creates salesforce_to_mysql service for you inside the `src` directory of your project.  \n\n## Testing\n\n### 1. Set up credentials for accessing Salesforce.\n\n- Visit [Salesforce](https:\/\/www.salesforce.com) and create a Salesforce account.\n\n- Create a connected app and obtain the following credentials:\n    - Base URL (Endpoint)\n    - Access Token\n    - Client ID\n    - Client Secret\n    - Refresh Token\n    - Refresh Token URL\n    \n#### 2. Create a database and set up credentials\n\n- If you have not installed MySQL in your computer, Please install MySql on your local computer.\nVisit [here](https:\/\/dev.mysql.com\/downloads\/) to download and install MySQL. After installing configure configure\na MySQL user and obtain username and password.\n\n- Create a new database and create a new `contacts` table. You can use following SQL script to create the table\nand insert a data row in to the table.\n```SQL\nUSE sf_company;\nCREATE TABLE IF NOT EXISTS contacts (\n    email varchar(255) NOT NULL,\n    first_name varchar(255) NOT NULL,\n    last_name varchar(255) NOT NULL,\n    last_modified timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n    PRIMARY KEY (email)\n);\nINSERT INTO contacts VALUES (\"johndoe@wso2.com\", \"John\", \"Doe\", CURRENT_TIMESTAMP);\n```\n\n#### 3. Add JDBC client connector\n\nSince we are using JDBC client for Database operations we need to create new directory called `lib` in the project\nroot directory and add `mysql-connector-java.jar` to the newly created `lib` directory. You can install\n`mysql-connector-java.jar` from [here](https:\/\/dev.mysql.com\/downloads\/connector\/j\/). After that you should edit\nyour `Ballerina.toml` file and mentioned the path to `mysql-connector-java.jar` as follows.\n\n```toml\n[project]\norg-name= \"wso2\"\nversion= \"0.1.0\"\n\n[dependencies]\n\n[platform]\ntarget = \"java11\"\n\n  [[platform.libraries]]\n  module = \"salesforce_to_mysql\"\n  path = \".\/lib\/mysql-connector-java.jar\"\n```\n\n#### 4. Add project configurations file\n\nAdd the project configuration file by creating a `ballerina.conf` file under the root path of the project structure.\nThis file should have following configurations. Add the obtained Salesforce configurations and Database\nconfigurations to the file.\n\n```\nSF_BASE_URL=\"<Salesforce base url (eg: https:\/\/ap15.salesforce.com)>\"\nSF_ACCESS_TOKEN=\"<Salesforce access token>\"\nSF_CLIENT_ID=\"<Salesforce client ID>\"\nSF_CLIENT_SECRET=\"<Salesforce client secret>\"\nSF_REFRESH_URL=\"<Salesforce refresh url (eg: https:\/\/login.salesforce.com\/services\/oauth2\/token)>\"\nSF_REFRESH_TOKEN=\"<Salesforce refresh token>\"\nJDBC_URL=\"<JDBC URL (eg: jdbc:mysql:\/\/localhost:3306\/sf_company)>\"\nDB_USERNAME=\"<MySQL database username>\"\nDB_PASSWORD=\"<MySQL database password>\"\nSCHEDULER_INTERVAL_IN_MILLIS=<Scheduler interval in milli-seconds (eg: 60000)>\n```\n\nLet’s build the module. Navigate to the project root directory and execute the following command.\n\n```bash\n$ bal build salesforce_to_mysql\n```\n\nThis creates the executables. Now run the `salesforce_to_mysql.jar` file created in the above step.\n\n```bash\n$ java -jar target\/bin\/salesforce_to_mysql.jar\n```\n\nYou will see the following log after successfully updating the database.\n\n```\n2019-09-26 17:41:27,708 INFO  [wso2\/sfdc_to_mysql_db] - service started...\n2019-09-26 17:41:32,094 INFO  [wso2\/sfdc_to_mysql_db] - Batch job SFDC -> MySQL has been completed.\n```",
+      "readme": "Template for Salesforce to MySQL using Ballerina\n\n# Salesforce to MySQL using Ballerina \n\nThis is a template for [Salesforce to MySQL Database tutorial](https:\/\/ei.docs.wso2.com\/en\/latest\/ballerina-integrator\/learn\/tutorials\/saas-integrations\/sfdc46\/salesforce-to-mysql-db\/1\/). Please refer to it for more details on what you are going to build here. This template provides a starting point for your scenario. \n\n## Using the Template\n\nRun the following command to pull the `salesforce_to_mysql` template from Ballerina Central.\n\n```\n$ bal pull wso2\/salesforce_to_mysql\n```\n\nCreate a new project.\n\n```bash\n$ bal new salesforce-to-mysql-db\n```\n\nNow navigate into the above project directory you created and run the following command to apply the predefined template \nyou pulled earlier.\n\n```bash\n$ bal add salesforce_to_mysql -t wso2\/salesforce_to_mysql\n```\n\nThis automatically creates salesforce_to_mysql service for you inside the `src` directory of your project.  \n\n## Testing\n\n### 1. Set up credentials for accessing Salesforce.\n\n- Visit [Salesforce](https:\/\/www.salesforce.com) and create a Salesforce account.\n\n- Create a connected app and obtain the following credentials:\n    - Base URL (Endpoint)\n    - Access Token\n    - Client ID\n    - Client Secret\n    - Refresh Token\n    - Refresh Token URL\n    \n#### 2. Create a database and set up credentials\n\n- If you have not installed MySQL in your computer, Please install MySql on your local computer.\nVisit [here](https:\/\/dev.mysql.com\/downloads\/) to download and install MySQL. After installing configure configure\na MySQL user and obtain username and password.\n\n- Create a new database and create a new `contacts` table. You can use following SQL script to create the table\nand insert a data row in to the table.\n```SQL\nUSE sf_company;\nCREATE TABLE IF NOT EXISTS contacts (\n    email varchar(255) NOT NULL,\n    first_name varchar(255) NOT NULL,\n    last_name varchar(255) NOT NULL,\n    last_modified timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n    PRIMARY KEY (email)\n);\nINSERT INTO contacts VALUES (\"johndoe@wso2.com\", \"John\", \"Doe\", CURRENT_TIMESTAMP);\n```\n\n#### 3. Add JDBC client connector\n\nSince we are using JDBC client for Database operations we need to create new directory called `lib` in the project\nroot directory and add `mysql-connector-java.jar` to the newly created `lib` directory.

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
