6
### Maven Project Coordination
7

8
Coordinates Maven-based builds and dependency management across all Java components and related language implementations.
9

10
```xml { .api }
11
<!-- Main project coordinates -->
12
<project>
13
  <groupId>org.apache.avro</groupId>
14
  <artifactId>avro-toplevel</artifactId>
15
  <version>1.12.0</version>
16
  <packaging>pom</packaging>
17
  <name>Apache Avro Toplevel</name>
18
  
19
  <!-- Includes Java implementation module -->
20
  <modules>
21
    <module>lang/java</module>
22
  </modules>
23
</project>
24
```
25

26
**Usage Examples:**
27

28
```xml
29
<!-- Include as parent POM for Avro-related projects -->
30
<parent>
31
  <groupId>org.apache.avro</groupId>
32
  <artifactId>avro-toplevel</artifactId>
33
  <version>1.12.0</version>
34
</parent>
35

36
<!-- Reference in dependency management -->
37
<dependencyManagement>
38
  <dependencies>
39
    <dependency>
40
      <groupId>org.apache.avro</groupId>
41
      <artifactId>avro-toplevel</artifactId>
42
      <version>1.12.0</version>
43
      <type>pom</type>
44
      <scope>import</scope>
45
    </dependency>
46
  </dependencies>
47
</dependencyManagement>
48
```
49

50
### Version Management
51

52
Centralized version control and synchronization across all language implementations and components.
53

54
```bash { .api }
55
# Version specification file
56
VERSION_FILE="share/VERSION.txt"
57

58
# Version format: MAJOR.MINOR.PATCH
59
# Example: 1.12.0
60
```
61

62
**Usage Examples:**
63

64
```bash
65
# Read current version
66
VERSION=$(cat share/VERSION.txt)
67
echo "Current Avro version: $VERSION"
68

69
# Use in build scripts
70
mvn versions:set -DnewVersion=$(cat share/VERSION.txt)
71

72
# Docker builds
73
docker build --build-arg AVRO_VERSION=$(cat share/VERSION.txt) .
74
```
75

76
### Cross-Language Build Coordination
77

78
Orchestrates builds across multiple programming languages with consistent tooling and standards.
79

80
```bash { .api }
81
# Main build script interface
82
function build() {
83
  language: string      # Target language (java, python, js, etc.)
84
  target: string       # Build target (compile, test, package, clean)
85
  flags?: string[]     # Additional build flags
86
  returns: BuildResult
87
}
88

89
# Build result structure
90
interface BuildResult {
91
  success: boolean
92
  language: string
93
  artifacts: string[]
94
  testResults?: TestSummary
95
  errors?: string[]
96
}
97

98
# Language detection and build dispatch
99
function detectLanguages(): string[]
100
function buildLanguage(language: string, target: string): BuildResult
101
function buildAll(target: string): BuildResult[]
102
```
103

104
**Usage Examples:**
105

106
```bash
107
# Build all language implementations
108
./build.sh
109

110
# Build specific language
111
./build.sh java
112

113
# Run tests across all languages
114
./build.sh test
115

116
# Clean all build artifacts
117
./build.sh clean
118

119
# Package for distribution
120
./build.sh package
121
```
122

123
### Development Environment Coordination
124

125
Manages development tools, configurations, and environments across the entire project ecosystem.
126

127
```yaml { .api }
128
# Development environment configuration
129
DevEnvironment:
130
  java:
131
    version: "11+"
132
    buildTool: "maven"
133
    testFramework: "junit"
134
  
135
  docker:
136
    baseImages:

145
    
146
  git:
147
    hooks: "share/githooks/"
148
    attributes: ".gitattributes"
149
```
150

151
**Usage Examples:**
152

153
```bash
154
# Setup development environment
155
./build.sh setup-dev
156

157
# Install git hooks
158
cp share/githooks/* .git/hooks/
159
chmod +x .git/hooks/*
160

161
# Use editor configurations
162
cp share/editors/vscode/* .vscode/
163

164
# Docker development environment
165
docker-compose up -d
166
```
167

168
### Project Structure Management
169

170
Defines and maintains the organizational structure for the multi-language Avro ecosystem.
171

172
```yaml { .api }
173

174
ProjectStructure:
175
  root: "/"
176
  
177
  languages:
178
    - path: "lang/java"
179
      primary: true
180
      buildSystem: "maven"
181
    - path: "lang/python" 
182
      buildSystem: "setuptools"
183
    - path: "lang/js"
184
      buildSystem: "npm"

    - path: "lang/csharp"
186
      buildSystem: "dotnet"
187
  
188
  shared:
189
    schemas: "share/schemas/"
190
    tests: "share/test/"
191
    docs: "doc/"
192
    version: "share/VERSION.txt"
193
  
194
  build:
195
    script: "build.sh"
196
    docker: "docker-compose.yml"
197
    maven: "pom.xml"
198
```
199

200
**Usage Examples:**
201

202
```bash
203
# Navigate project structure
204
ls lang/                    # List all language implementations
205
ls share/schemas/          # Browse shared schemas
206
ls share/test/             # Access shared test data
207

208
# Find language-specific components
209
find lang/ -name "pom.xml"       # Java Maven projects
210
find lang/ -name "package.json"  # JavaScript packages
211
find lang/ -name "setup.py"      # Python packages
212
```
