||
| ## Build Requirements | ||
|
|
||
| ### Operating Systems | ||
|
|
||
| Ice for Java builds and runs properly on Windows, macOS, and any recent | ||
| Linux distribution, and is fully supported on the platforms listed on the | ||
| [supported platforms][2] page. | ||
|
|
||
| ### Slice to Java Compiler | ||
|
|
||
| You need the Slice to Java compiler to build Ice for Java and also to use | ||
| Ice for Java. The Slice to Java compiler (`slice2java`) is a command-line tool | ||
| written in C++. You can build the Slice to Java compiler from source, or | ||
| alternatively you can install an Ice [binary distribution][1] that includes | ||
| this compiler. | ||
|
|
||
| ### Java Version | ||
|
|
||
| Ice for Java requires J2SE 1.7.0 or later. | ||
|
|
||
| Make sure that the `javac` and `java` commands are present in your PATH. | ||
|
|
||
| ### Gradle | ||
|
|
||
| Ice for Java uses the [Gradle][3] build system, and includes the Gradle wrapper | ||
| in the distribution. You cannot build the Ice for Java source distribution | ||
| without an Internet connection. Gradle will download all required packages | ||
| automatically from Maven Central repository located at | ||
| http://central.maven.org/maven2/ | ||
|
|
||
| ### Bzip2 Compression | ||
|
|
||
| Ice for Java supports protocol compression using the bzip2 classes included | ||
| with [Apache Commons Compress][4]. | ||
|
|
||
| The Maven package id for the commons-compress JAR file is as follows: | ||
|
|
||
| ``` | ||
| groupId=org.apache.commons, version=1.20, artifactId=commons-compress | ||
| ``` | ||
|
|
||
| The demos and tests are automatically setup to enable protocol compression by | ||
| adding the commons-compress JAR to the manifest class path. For your own | ||
| applications you must add the commons-compress JAR to the application CLASSPATH | ||
| to enable protocol compression. | ||
|
|
||
| ## Building Ice for Java | ||
|
|
||
| The build system requires the Slice to Java compiler from Ice for C++. If you | ||
| have not built Ice for C++ in this source distribution, you must set the | ||
| `ICE_HOME` environment variable with the path name of your Ice installation. For | ||
| example, on Linux: | ||
|
|
||
| ``` | ||
| export ICE_HOME=/opt/Ice-3.7.10 (For local build) | ||
| export ICE_HOME=/usr (For RPM installation) | ||
| ``` | ||
|
|
||
| On Windows: | ||
|
|
||
| ``` | ||
| set ICE_HOME=C:\Program Files\ZeroC\Ice-3.7.10 (MSI installation) | ||
| ``` | ||
|
|
||
| On Windows if you are using Ice for C++ from a source distribution, you must set | ||
| the `CPP_PLATFORM` and `CPP_CONFIGURATION` environment variables to match the | ||
| platform and configuration used in your C++ build: | ||
|
|
||
| ``` | ||
| set CPP_PLATFORM=x64 | ||
| set CPP_CONFIGURATION=Debug | ||
| ``` | ||
|
|
||
| The supported values for `CPP_PLATFORM` are `Win32` and `x64` and the supported | ||
| values for `CPP_CONFIGURATION` are `Debug` and `Release`. | ||
|
|
||
| Before building Ice for Java, review the settings in the file | ||
| `gradle.properties` and edit as necessary. | ||
|
|
||
| To build Ice, all services, and tests, run | ||
|
|
||
| ``` | ||
| gradlew build | ||
| ``` | ||
|
|
||
| Upon completion, the Ice JAR and POM files are placed in the `lib` subdirectory. | ||
|
|
||
| If at any time you wish to discard the current build and start a new one, use | ||
| these commands: | ||
|
|
||
| ``` | ||
| gradlew clean | ||
| gradlew build | ||
| ``` | ||
|
|
||
| ## Installing Ice for Java | ||
|
|
||
| To install Ice for Java in the directory specified by the `prefix` variable in | ||
| `gradle.properties` run the following command: | ||
|
|
||
| ``` | ||
| gradlew install | ||
| ``` | ||
|
|
||
| The installation installs the following JAR files to `<prefix>/lib`. | ||
|
|
||
| ``` | ||
| glacier2-compat-3.7.10.jar | ||
| ice-compat-3.7.10.jar | ||
| icebox-compat-3.7.10.jar | ||
| icebt-compat-3.7.10.jar | ||
| icediscovery-compat-3.7.10.jar | ||
| icegrid-compat-3.7.10.jar | ||
| icelocatordiscovery-compat-3.7.10.jar | ||
| icepatch2-compat-3.7.10.jar | ||
| icestorm-compat-3.7.10.jar | ||
| ``` | ||
|
|
||
| POM files are also installed for ease of deployment to a Maven-based | ||
| distribution system. | ||
|
|
||
| ## Running the Java Tests | ||
|
|
||
| Some of the Ice for Java tests employ applications that are part of the Ice for | ||
| C++ distribution. If you have not built Ice for C++ in this source distribution | ||
| then you must set the `ICE_HOME` environment variable with the path name of your | ||
| Ice installation. On Linux or macOS: | ||
|
|
||
| ``` | ||
| export ICE_HOME=/opt/Ice-3.7.10 (For local build) | ||
| export ICE_HOME=/usr (For RPM installation) | ||
| ``` | ||
|
|
||
| On Windows: | ||
|
|
||
| ``` | ||
| set ICE_HOME=C:\Program Files\ZeroC\Ice-3.7.10 | ||
| ``` | ||
|
|
||
| Python is required to run the test suite. To run the tests, open a command | ||
| window and change to the top-level directory. At the command prompt, execute: | ||
|
|
||
| ``` | ||
| python allTests.py | ||
| ``` | ||
|
|
||
| If everything worked out, you should see lots of `ok` messages. In case of a | ||
| failure, the tests abort with `failed`. | ||
|
|
||
| ## Building the Ice for Android Tests | ||
|
|
||
| The `test/android/controller` directory contains an Android Studio project | ||
| for the Ice test suite controller. | ||
|
|
||
| ### Build Requirements | ||
|
|
||
| Building any Ice application for Android requires Android Studio and the Android | ||
| SDK build tools. We tested with the following components: | ||
|
|
||
| - Android Studio Electric Eel | ||
| - Android SDK 33 | ||
|
|
||
| Ice requires at minimum API level 21: | ||
|
|
||
| - Android 5 (API21) | ||
|
|
||
| ### Building the Android Test Controller | ||
|
|
||
| You must first build Ice for Java refer to [Building Ice for Java](#building-ice-for-java-1) | ||
| for instructions, then follow these steps: | ||
|
|
||
| 1. Start Android Studio | ||
| 2. Select "Open an existing Android Studio project" | ||
| 3. Navigate to and select the "android" subdirectory | ||
| 4. Click OK and wait for the project to open and build | ||
|
|
||
| To build the tests against the Ice binary distribution you must set `ICE_BIN_DIST` environment | ||
| variable to `all` before starting Android Studio. | ||
|
|
||
| ## Running the Android Tests | ||
|
|
||
| The Android Studio project contains a `controller` app for the Ice test | ||
| suite. Prior to running the app, you must disable Android Studio's Instant Run | ||
| feature, located in File / Settings / Build, Execution, Deployment / | ||
| Instant Run. | ||
|
|
||
| Tests are started from the dev machine using the `allTests.py` script, similar | ||
| to the other language mappings. The script uses Ice for Python to communicate | ||
| with the Android app, therefore you must build the [Python mapping] | ||
| (../../python) before continuing. | ||
|
|
||
| You also need to add the `tools\bin`, `platform-tools` and `emulator` | ||
| directories from the Android SDK to your PATH. On macOS, you can use the | ||
| following commands: | ||
|
|
||
| ``` | ||
| export PATH=~/Library/Android/sdk/cmdline-tools/latest/bin:$PATH | ||
| export PATH=~/Library/Android/sdk/platform-tools:$PATH | ||
| export PATH=~/Library/Android/sdk/emulator:$PATH | ||
| ``` | ||
|
|
||
| On Windows, you can use the following commands: | ||
|
|
||
| ``` | ||
| set PATH=%LOCALAPPDATA%\Android\sdk\cmdline-tools\latest\bin;%PATH% | ||
| set PATH=%LOCALAPPDATA%\Android\sdk\platform-tools;%PATH% | ||
| set PATH=%LOCALAPPDATA%\Android\sdk\emulator;%PATH% | ||
| ``` | ||
|
|
||
| Run the tests with the Android emulator by running the following command: | ||
|
|
||
| ``` | ||
| python allTests.py --android --controller-app | ||
| ``` | ||
|
|
||
| To run the tests on a Android device connected through USB, you can use | ||
| the `--device=usb` option as shown below: | ||
|
|
||
| ``` | ||
| python allTests.py --android --device=usb --controller-app | ||
| ``` | ||
|
|
||
| To connect to an Android device that is running adb you can use the | ||
| `--device=<ip-address>` | ||
|
|
||
| ``` | ||
| python allTests.py --android --device=<ip-address> --controller-app | ||
| ``` | ||
|
|
||
| To run the tests against a `controller` application started from Android | ||
| Studio you should omit the `--controller-app` option from the commands above. | ||
