Launch4j 重定向下载 java 版本

Question

我在 Java 项目中使用 Maven 的 Launch4j 插件。当我在未安装 Java 的 Windows 系统上将项目编译为 exe 和运行时，它会重定向（自动打开网络浏览器）以下载 Java 但使用 32 位版本。我想重定向以下载 64 位最新版本。可能吗？

我在 Maven 中的插件定义看起来像

<plugin>
    <groupId>com.akathist.maven.plugins.launch4j</groupId>
    <artifactId>launch4j-maven-plugin</artifactId>
    <version>1.7.11</version>
    <executions>
        <execution>
            <id>l4j-gui</id>
            <phase>package</phase>
            <goals>
                <goal>launch4j</goal>
            </goals>
            <configuration>
                <headerType>gui</headerType>
                <outfile>target/Project.exe</outfile>
                <jar>target/Project.jar</jar>
                <priority>high</priority>
                <errTitle>project</errTitle>
                <classPath>
                    <mainClass>com.project.Main</mainClass>
                    <preCp>libs/*.jar</preCp>
                </classPath>
                <jre>
                    <minVersion>1.8.0_101</minVersion>
                </jre>
                <icon>${basedir}/build-resources/win/application-${ENV}.ico</icon>
            </configuration>
        </execution>
    </executions>
</plugin>

我尝试在 <jar>...</jar> 中添加 <runtimeBits>64</runtimeBits>，当运行 exe 文件弹出时显示 "The application requries a Java Runtime Environment 1.8.0_101 (64-bit)"，点击确定后，它重定向到下载 32 位版本，页面地址 https://java.com/pl/download/

我也试过在<jar>...</jar>中添加<bundledJre64Bit>true</bundledJre64Bit>但是无法结束编译和return错误如下

Answer 1

此处提供了详细信息 - 看看是否有帮助

http://launch4j.sourceforge.net/docs.html

<bundledJre64Bit>true|false</bundledJre64Bit>
<bundledJreAsFallback>true|false</bundledJreAsFallback>
<runtimeBits>64|64/32|32/64|32</runtimeBits>

Answer 2

解决方案

在 <jre>...</jre> 之前只需添加 <downloadUrl>https://java.com/en/download/manual.jsp</downloadUrl> 即可。

当用户可以根据系统选择 java 版本时，将我们重定向到页面，并且必须通过在 <jre>... 括号中添加 <runtimeBits>64</runtimeBits> 来下载哪个版本。
