Android项目集成Geotools库构建失败的排查与解决

问题背景 #

开发Android项目时引入GeoTools库后构建失败，相关配置如下：

Gradle构建工具版本 #

classpath 'com.android.tools.build:gradle:7.0.4'

原仓库配置 #

repositories {
    maven { url "https://repo.osgeo.org/repository/release/" }  // 原使用的仓库地址
    mavenLocal()
    mavenCentral()
    google()
    gradlePluginPortal()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    maven { url "https://oss.sonatype.org/content/repositories/releases/" }
    maven { url "https://jitpack.io" }
}

依赖配置 #

dependencies {
    implementation 'org.geotools:gt-main:28.0'  // GeoTools核心依赖
    testImplementation "junit:junit:$junitVersion"
}

构建错误信息 #

执行构建时触发如下错误：

> Task :android:mergeDebugJavaResource FAILED
Execution failed for task ':android:mergeDebugJavaResource'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
   > 2 files found with path 'plugin.xml' from inputs:
      - C:\gradle\caches\transforms-3\4ee35d2fa6e19aaa21a107f9d19d12b8\transformed\jetified-org.eclipse.emf.ecore.xmi-2.15.0.jar
      - C:\gradle\caches\transforms-3\c4ca9df1db430b1e56c1959084f034a1\transformed\jetified-org.eclipse.emf.ecore-2.15.0.jar
     Adding a packagingOptions block may help, please refer to

     for more information

曾尝试降级GeoTools版本，未解决问题。

解决方案 #

通过以下两步操作解决构建失败问题：

1. 修改GeoTools仓库地址
   将原仓库地址替换为：https://repo.osgeo.org/repository/geotools-releases/

2. 添加packagingOptions配置
   在项目的android配置块中添加如下内容，排除冲突的资源文件：

android {
    packagingOptions {
        exclude 'AndroidManifest.xml'
        exclude 'plugin.xml'
        exclude 'about.ini'
        exclude 'about.mappings'
        exclude 'modeling32.png'
        exclude 'about.properties'
        exclude 'plugin.properties'
    }
}
