Question

我为我的项目启动了launch4j配置。当我在windowsXP上开发它时，我用它回来了。现在我需要它在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] 21 RCDATA BEGIN "http://java.com/download\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launch4j执行时，找到了ld和windres，输出变为：

对于那些经历过：

的人

error=2, No such file or directory

在64位Linux上运行 windres 时出现问题，您需要安装32位库。在Linux Mint上我安装了包ia32-libs：

sudo apt-get install ia32-libs

Answer 2

当您的当前目录不是launch4j目录时会发生此错误，正如Leo所说。

Launch4j试图通过查找找到自己的安装目录 launch4j.properties的类路径。这是在Util.java中完成的 getJarBaseDir（）方法。最近更改了这些内容：

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（）没有返回本地文件URI的“file：”部分 - 它只返回以/开头的URI的路径部分。我将最后两行更改为此，然后开始工作：

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

注意5 - ＆gt;在子字符串中为0因为我们不再需要删除“file：”部分。我不得不将build.xml.prod重命名为build.xml以编译launch4j，但除此之外它工作得很好。

我遇到了同样的问题并且无法正确设置路径/类路径，但作为一种解决方法，我在launch4j目录中创建了Ant构建，并且我能够使其生成可执行文件。

Answer 4

我也有这个问题，我通过修改launch4j代码修复了它在类Launch4JTask.java中，我替换了行

final Builder b = new Builder(Log.getAntLog());

这一个

final Builder b = new Builder(Log.getAntLog(), new File(getOwningTarget().getProject().getProperty("launch4j.bindir")));

通过此更改，我可以在我的ant构建脚本中指定Launch4j的路径，就像那样

<property name="launch4j.bindir" location="../tools/launch4j/" />

问候，-chris -

我在Maven中构建launch4j时遇到了类似的问题：

...
[INFO] launch4j: (longPathIn.m2Repository)\windres.exe: can't popen `type  (longPathToTemp)\Temp\launch4j8580185391499327059rc': No error
[ERROR] 
net.sf.launch4j.BuilderException: net.sf.launch4j.ExecException: Exec failed(1): [Ljava.lang.String;@9f1fb5
at net.sf.launch4j.Builder.build(Builder.java:145)
...

清洁系统变量ComSpec后，它开始正常工作：

was: ComSpec=%SystemRoot%\system32\cmd.exe;c:\Program Files (x86)\NSIS\NSIS.exe
now: ComSpec=%SystemRoot%\system32\cmd.exe

似乎NSIS在那里插入了自己，而不是我。

Launch4j / windres：如何正确设置路径？
