Develop Java applications. Includes the JDK and Java extensions.

While this definition should work unmodified, you can select the version of Java the container uses by updating the VARIANT arg in the included devcontainer.json (and rebuilding if you've already created the container).

"args": { "VARIANT": "14" }

Note that only the integrated terminal is supported by the Remote - Containers extension. You may need to modify launch.json configurations to include the following value if an external console is used.

"console": "integratedTerminal"

You can opt to install a version of Maven or Gradle by adding "INSTALL_MAVEN: "true" or "INSTALL_GRADLE: "true" to build args in .devcontainer/devcontainer.json. Both of these are set by default. For example:

"args": { 
   "VARIANT": "11",
   "INSTALL_GRADLE": "true",
   "INSTALL_MAVEN": "true"
}

Remove the appropriate arg or set its value to "false" to skip installing the specified tool.

You can also specify the verison of Gradle or Maven if needed.

"args": { 
   "VARIANT": "11",
   "INSTALL_GRADLE": "true",
   "MAVEN_VERSION": "3.6.3",
   "INSTALL_MAVEN": "true",
   "GRADLE_VERSION": "5.4.1"
}

And if you'd like the download SHA to be checked, you can add it as well.

"args": {
   "VARIANT": "11",
   "INSTALL_MAVEN": "true",
   "MAVEN_VERSION": "3.6.3",
   "MAVEN_DOWNLOAD_SHA": "c35a1803a6e70a126e80b2b3ae33eed961f83ed74d18fcd16909b2d44d7dada3203f1ffe726c17ef8dcca2dcaa9fca676987befeadc9b9f759967a8cb77181c0",
   "INSTALL_GRADLE": "true",
   "GRADLE_VERSION": "5.4.1",
   "GRADLE_DOWNLOAD_SHA": "7bdbad1e4f54f13c8a78abc00c26d44dd8709d4aedb704d913fb1bb78ac025dc"
}

Given how frequently web applications use Node.js for front end code, this container also includes an optional install of Node.js. You can enable installation and change the version of Node.js installed or disable its installation by updating the args property in .devcontainer/devcontainer.json.

"args": {
   "VARIANT": "11",
    "INSTALL_NODE": "true",
    "NODE_VERSION": "10",
}
