Required:

• Java 17 (currently the only supported Java release)
• Maven 3.6.3+

The launch scripts enforce Java 17 as the minimum runtime. This check does not qualify later Java releases; build HugeGraph with Java 17 unless another release is explicitly listed as supported.

The published hugegraph-common and hugegraph-rpc libraries use Java 11 bytecode for downstream compatibility. Their build and tests still run on Java 17; this library bytecode target does not lower HugeGraph's runtime requirement.

See the Server runtime guide for the upgraded runtime, client configuration and compatibility checks.

To build without executing tests: mvn clean package -Dmaven.test.skip=true

The standard distribution does not include org.apdplat:word:1.3. It is a provided dependency used to compile and test the optional word analyzer. The default analyzer remains ikanalyzer; the shipped graph configurations use jieba, and neither requires the word library.

Obtain the GPLv3-licensed external component from Maven Central.

To use word, supply word-1.3.jar separately in the Server's lib/ directory and restart the Server. Select it in the graph configuration with a supported mode, for example:

search.text_analyzer=word
search.text_analyzer_mode=PureEnglish

Selecting word without its external library fails with a configuration error identifying the missing optional dependency. Other analyzers remain available. Applications using Struct directly must add the same dependency to their runtime classpath when selecting word.

To build without executing tests:

1. Click on "File" -> "Open", choose your project location.
2. Open maven view by click "View" -> "Tool Windows" -> "Maven Projects".
3. Choose root module "hugegraph: Distributed Graph Database", unfold the menu of "Lifecycle".
4. Click the "Toggle 'Skip Tests' Mode" button which is located on the top navibar of "Maven Projects" window to skip tests.
5. Double click "package" or "install" to build a project.

Could also refer Dev-In-IDEA for more details.

Note: this has only been tested on Eclipse Neon.2 Release (4.6.2) with m2e (1.7.0.20160603-1933) and m2e-wtp (1.3.1.20160831-1005) plugin.

To build without executing tests:

1. Right-click on your project -> "Run As..." -> "Run Configurations..."
2. On "Goals", populate with install
3. Select the options Update Snapshots and Skip Tests
4. Before clicking "Run", make sure that Eclipse knows where JAVA_HOME is. In the same window, go to "Environment" tab and click "New".
5. Under "Name:", add JAVA_HOME
6. Under "Value:", add the path where java is located
7. Click "OK"
8. Then click "Run"

To find the Java binary in your environment, run the appropriate command for your operating system:

• Linux/macOS: which java
• Windows: for %i in (java.exe) do @echo. %~$PATH:i
