Java 应用程序 Bundled for Mac 无法启动

Question

我正在按照其他答案的建议使用 jarbundler 2.2.0，因为应用程序应该在 Apple 的 JRE 1.6 上运行。

bundle 似乎是正确的，显示了适当的图标，但点击它没有任何反应。如果我进入它的内容并尝试双击带有指定主文件的 jar，就可以正常工作。

有没有办法查看发生了什么？我能看到某种错误或日志吗？

编辑请求的 Info.plist。由于代码是私有(private)的，我用 Application 替换了一些东西:

PkgInfo 的内容:

APPL????

在 Application.app/Contents/MacOS 上，我有来自 Mac 机器的 JavaApplicationStub。

生成的文件结构:

Answer 1

那些反斜杠肯定是错误的，因为 Mac OS 是 Unix。应该是:

  <array>
    <string>$JAVAROOT/Application.jar</string>
    <string>$JAVAROOT/lib/lib1.jar</string>
    <string>$JAVAROOT/lib/lib2.jar</string>
  </array>

既然您说您是在 Windows 上执行此操作，那么我要检查的另一件事是文件权限。特别是这些文件:

• MacOS/JavaApplicationStub (rwxrwxr-x)
• Resources/Java/Application.jar (-rw-rw-r--)
• Resources/Java/lib/lib1.jar (-rw-rw-r--)
• Resources/Java/lib/lib2.jar (-rw-rw-r--)

最后，1.6* 的 JVMVersion 是 not recommended .尝试改用 1.5+ 或 1.6+，因为它可能更兼容。

排除以上所有情况，问题一定出在 JavaApplicationStub 上。注意，来自 JarBundler 页面:

When the JarBundler ANT task is used under Windows or Linux, a copy of the JavaApplicationStub must be supplied by the developer. This cannot be built from source but must be obtained from a Mac OS X system.

Java 启动 stub 的一个已知问题

In early 2006 an Apple upgrade to Quicktime (7.0.4) caused older versions of "JavaApplicationStub" to fail to start up. These old copies came from developers who first created the application bundle as a directory and then created new applications by replacing the JAR files within the bundle and not replacing "JavaApplicationStub" with a more current copy.
