我在我的项目中使用TwelveMonkeys库(com.twelvemonkeys.imageio:imageio-tiff:3.1.1
)。另外,我正在使用 Maven 和maven-dependency-plugin来构建我的项目,我正在配置它:
<plugin>
<!-- Get the dependencies jar files to a common place, for jar signing -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeArtifactIds>commons-net,imageio-psd,imageio-tiff</includeArtifactIds>
<!-- <includeGroupIds>com.twelvemonkeys.imageio</includeGroupIds> -->
<outputDirectory>${project.build.directory}/classes</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
该项目正在正确编译,但它在运行时抱怨ClassNotFoundException: com.twelvemonkeys.io.enc.Decoder
。我猜,includeArtifactIds
不包括其中指定的库的依赖项(嵌套依赖项)。这就是我在pom.xml中包含 TwelveMonkeys 库的方法:
<dependencies>
...
<dependency>
<groupId>com.twelvemonkeys.imageio</groupId>
<artifactId>imageio-psd</artifactId>
<version>3.1.1</version>
</dependency>
<dependency>
<groupId>com.twelvemonkeys.imageio</groupId>
<artifactId>imageio-tiff</artifactId>
<version>3.1.1</version> <!-- Alternatively, build your own version -->
</dependency>
...
</dependencies>
有人可以建议我如何在我的FINAL FAT JAR文件中包含imageio-tiff
和imageio-psd
所依赖的所有库?只需要有一个更好的方法来指定“包含所有依赖项,并具有自己的依赖项”。

我也使用ProGaurd进行混淆,配置如下:
<plugin>
<groupId>com.github.wvengen</groupId>
<artifactId>proguard-maven-plugin</artifactId>
<version>2.0.10</version>
<dependencies>
<dependency>
<groupId>net.sf.proguard</groupId>
<artifactId>proguard-base</artifactId>
<version>5.2</version>
<scope>runtime</scope>
</dependency>
</dependencies>
<executions>
<execution>
<phase>package</phase>
<goals><goal>proguard</goal></goals>
</execution>
</executions>
<configuration>
<proguardVersion>5.2</proguardVersion>
<obfuscate>true</obfuscate>
<injar>${project.build.finalName}.jar</injar>
<outjar>${project.build.finalName}.jar</outjar>
<outputDirectory>${project.build.directory}</outputDirectory>
<options>
<option>-allowaccessmodification</option>
...
<option>-keep public class com.twelvemonkeys.** { *; }</option>
</options>
<libs>
<lib>${java.home}/lib/rt.jar</lib>
<lib>${java.home}/lib/jsse.jar</lib>
<lib>${java.home}/lib/jce.jar</lib>
<lib>${java.home}/lib/plugin.jar</lib>
</libs>
</configuration>
</plugin>
答案 0 :(得分:0)
这是我的pom.xml的一部分,用于构建包含所有依赖项的.JAR文件。
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin
</plugins>
</build>
并添加到您的依赖项:
<scope>compile</scope>
我通常按以下顺序构建一个jar:
这适用于我包括所有库。
