我在使用简单的Java程序制作可执行jar时遇到问题。
我关注了these Maven instructions并修改了我的pom.xml
:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation=
"org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>package.MyClass</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
执行install
目标时,我可以阅读以下内容:
[INFO] Replacing /home/project-1.0.0.jar with /home/project-1.0.0-shaded.jar
但是我在那个位置找到的只是project-1.0.0.jar
,实际上包含了依赖关系 - 并且具有正确的大小 - 但是当我试图用我的jre执行它时,它说:
The file '/home/project-1.0.0.jar' is not marked as executable.
因此没有任何东西可以执行!
如何让我的jar正确执行?
感谢您的帮助!

给出 pom.xml 来创建可执行jar文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

我有一个使用程序集插件的简单解决方案。这个解决方案将创建一个jar(target / $ {project.groupdId} - $ {project.artifactId} - $ {project.version} .jar):
在你的pom文件中声明:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<archive>
<manifest>
<mainClass>package.MyClass</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-executable-jar</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
我希望我能帮到你! 干杯!
