Launch4j / windres：如何正确设置路径？

Question

我为我的项目配置了 launch4j。当我在 windowsXP 上开发时，我使用了它，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] 18 RCDATA BEGIN "0\0" END
 [launch4j] 25 RCDATA BEGIN "512\0" END
 [launch4j] 27 RCDATA BEGIN "1024\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

当我在launch4j-execution中添加bindir="tools/launch4j/bin"时，找到了ld和windres，输出变为：

对于那些体验过的人：

error=2, No such file or directory

在 64 位 Linux 上运行 windres 时的问题，您需要安装 32 位库。在 Linux Mint 上，我安装了 ia32-libs 包：

sudo apt-get install ia32-libs

Answer 2

如 Leo 所述，当您的当前目录不是 launch4j 目录时会发生此错误。

Launch4j 尝试通过查看 launch4j.properties 的类路径。这是在 Util.java 中完成的，位于 getJarBaseDir() 方法。最近更改为具有以下几行：

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('!'));

请注意子字符串中的 5 -> 0，因为我们不再需要删除 "file:" 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。

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

Answer 4

我也遇到了这个问题，我通过修改 launch4j 代码解决了这个问题。
在 Class Launch4JTask.java 中，我替换了这一行

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

这个

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

通过这个更改，我可以像这样在我的 ant 构建脚本中指定 Launch4j 的路径

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

你好，-克里斯-

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)
...

清理系统变量ComSpec后开始正常工作：

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

似乎是 NSIS 自己插入了那里，而不是我。
