Launch4j / windres:如何正确设置路径？

Question

我已经为我的项目配置了launch4j。当我在windowsXP上开发时，我重新使用了它，它在那里工作。现在我也需要它在mac上构建：

我的build.xml：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project default="create-exe">

    <property name="platform" value="win32"/>
    <property name="launch4j.dir" location="${basedir}/tools/launch4j/" />

    <include file="create-jar.xml" as="sub"/>

    <target name="create-exe" depends = "sub.create-jar">
        <launch4j configFile="launch4j-config.xml" />
        <delete file="client.win32.jar"/>
    </target>

    <taskdef name="launch4j" classname="net.sf.launch4j.ant.Launch4jTask">
        <classpath>
            <pathelement path="tools/launch4j/launch4j.jar"/>
            <pathelement path="tools/launch4j/lib/xstream.jar"/>
        </classpath>
    </taskdef>
</project>

我得到以下输出：

create-exe:
 [launch4j] Compiling resources
 [launch4j] Generated resource file...
 [launch4j] LANGUAGE 0, 1
 [launch4j] 2 RCDATA BEGIN "1.6.0\0" END

 [launch4j] 20 RCDATA BEGIN "32\0" END
 [launch4j] 9 RCDATA BEGIN "true\0" END
 [launch4j] 101 RCDATA BEGIN "An error occurred while starting the application.\0" END
 [launch4j] 102 RCDATA BEGIN "This application was configured to use a bundled Java Runtime Environment but the runtime is missing or corrupted.\0" END
 [launch4j] 103 RCDATA BEGIN "This application requires a Java Runtime Environment\0" END
 [launch4j] 104 RCDATA BEGIN "The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.\0" END
 [launch4j] 17 RCDATA BEGIN "true\0" END

BUILD FAILED

当我将bindir="tools/launch4j/bin"添加到启动4j-execution中时，找到ld和windres，并且输出变为：

Answer 1

我遇到了同样的问题，无法正确设置路径/类路径，但作为一种变通方法，我在launch4j目录中创建了Ant构建，并且能够让它生成可执行文件。

Answer 2

对于那些经历过以下情况的人：

error=2, No such file or directory

问题在64位Linux上运行windres时，需要安装32位库。在Linux Mint上，我使用以下命令安装了ia32-libs包：

sudo apt-get install ia32-libs

Answer 3

正如Leo所指出的，当您的当前目录不是launch4j目录时，会出现此错误。

Launch4j试图通过查找launch4j.properties的类路径来查找自己的安装目录。这是在getJarBaseDir()方法顶部的Util.java中完成的。最近将其更改为以下几行：

URI uri = new URI(Util.class.getClassLoader()
    .getResource(Launch4jProperties)
    .getFile());

String path = uri.getPath();

if (path.startsWith("file:")) {
  String jarPath = path.substring(5,path.lastIndexOf('!'));

问题是uri.getPath()不返回本地文件URI的" file :“部分--它只返回以/开头的URI的路径部分。我把最后两行改成这样，它开始工作了：

if (path.startsWith("/")) {
  String jarPath = path.substring(0, path.lastIndexOf('!'));

注意substring中的5file 0，因为我们不再需要删除“->：”部分。为了编译launch4j，我不得不将build.xml.prod重命名为build.xml，但除此之外，它工作得很好。
