无法从 jar 文件启动 JavaFx 应用程序。 Class 未发现异常

Question

我想从 jar 启动我的 java fx 应用程序，但我发现了以下错误：

应用程序启动方法异常

我使用 dagger2 进行依赖注入，在 start() 方法中我的应用程序组件正在初始化。很奇怪，因为我在 pom 文件中包含了 javax.inject 依赖项。语言级别 - 8。JDK/JRE 版本 1.8.0_192。工件 - java fx 应用程序。

Answer 1

您需要确保您的容器提供依赖性 javax.inject 或者简单地删除 <scope>provided</scope>:

<dependency>
  <groupId>javax.inject</groupId>
  <artifactId>javax.inject</artifactId>
  <version>1</version>
</dependency>

此外，最好为 maven-compiler-plugin:

显式设置 source 和 target 属性

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <annotationProcessorPaths>
            <path>
                <groupId>com.google.dagger</groupId>
                <artifactId>dagger-compiler</artifactId>
                <version>2.16</version>
            </path>
        </annotationProcessorPaths>
    </configuration>
</plugin>

如果您想运行您的应用程序使用此命令 java -jar MyApp.jar 您需要在 -cp 标志或 jar 内部提供所有依赖项。

要用整个依赖项列表打包你的 jar，你可以使用 maven-assembly-plugin，像这样：

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
        <archive>
        <manifest>
            <mainClass>
                !!!com.package.path.ClassWithMainMethodName!!!
            </mainClass>
        </manifest>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
</plugin>
