Eclipse 无法以编程方式编译 ant 脚本
我有一个 Ant 脚本,我想使用我制作的按钮来执行它。现在的问题是我会收到一条错误消息:
构建失败
X:\eclipseMT\runtime-workspace\testTest\diagram1_Sc2_TestScript.xml:68: 找不到javac编译器; com.sun.tools.javac.Main 不上 类路径。也许 JAVA_HOME 没有 指向 JDK。目前已设定 到“C:\程序 文件\Java\jdk1.6.0_12\jre"
我非常确定我的类路径是正确的,并且我可以使用 Eclipse 内部 Ant 执行器执行相同的脚本。
这是我的 ant 脚本:

这是我的按钮代码:

consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
} catch (Throwable t) {
t.printStackTrace();
p.fireBuildFinished(t);
return false;
}
I have an Ant script that I would like to execute using a button that I made. The problem now is that I would get an error saying:
BUILD FAILED
X:\eclipseMT\runtime-workspace\testTest\diagram1_Sc2_TestScript.xml:68:
Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the
classpath. Perhaps JAVA_HOME does not
point to the JDK. It is currently set
to "C:\Program
Files\Java\jdk1.6.0_12\jre"
I'm pretty sure that my classpath is correct and I can execute the same script using Eclipse internal Ant executor.
This is my ant script:

This is my button code:

consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
} catch (Throwable t) {
t.printStackTrace();
p.fireBuildFinished(t);
return false;
}

它抱怨javac,无法找到javac..你的JAVA_HOME(C:\ Program Files \ Java \ jdk1.6.0_12 \ jre)仅指向“jre”而不是java编译器(javac)。将 JAVA_HOME 设置为“C:\Program Files\Java\jdk1.6.0_12\bin”(其中有 javac 和 jre),它应该可以工作。 :-)

It's complaining about javac, unable to find javac.. your JAVA_HOME(C:\Program Files\Java\jdk1.6.0_12\jre) is pointing to only "jre" not to java compiler(javac). Set you JAVA_HOME to "C:\Program Files\Java\jdk1.6.0_12\bin"(which has both javac and jre) and it should work. :-)

一位朋友给我参考了这个早期的问题: Setting JAVA_HOME when running Ant来自 Java
问题基本上出在 ant 上,因为它将 java.home 指向“jre”而不是“jdk”。每次调用 ant 执行时它都会被覆盖。
添加:
fork="yes"
解决办法是在每个编译脚本中
,并添加:
p.setProperty("java.home", "C:\\Program Files\\Java\\ jdk1.6.0_26");
到java执行代码。
希望这对其他人有帮助:D
A friend give me a reference to this earlier question: Setting JAVA_HOME when running Ant from Java
The problem basicly is with ant because it has point java.home to 'jre' instead of 'jdk'. It got overwritten everytime ant was call to execute.
The solution is to add:
fork="yes"
to each compilation script and add:
p.setProperty("java.home", "C:\\Program Files\\Java\\jdk1.6.0_26");
to the java execution code.
Hope this help others :D
