javac not recognized

巧了我就是萌 提交于 2019-11-30 16:57:15
问题 What can I do when I keep receiving the error 'javac' is not recognized as an internal or external command, operable program or batch file when I want to compile my jar or .class file? Thanks 回答1: Make sure %JAVA_HOME%/bin is on your %PATH% (or $JAVA_HOME on the $PATH in *nix). 回答2: It means that it is not in your path. You have the following options: 1) Change to the directory where javac lives before calling it. 2) Use the full path to javac when making the call, e.g. C:\java\jdk1.6.0_12

How to tell eclipse to add-exports when compiling

别说谁变了你拦得住时间么 提交于 2019-11-30 15:59:05
Is it possible to tell eclipse to add the following command line option: --add-exports jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED when compiling. I think it may also be needed when running tests. Is it also possible to remove this message: Note that I tried to add those to the VM options of one of my unit tests but that did not work. Go to Project > Properties: Java Build Path , tab Libraries Select the JRE > Is modular node and click Edit... Go to the tab Details In the Added exports section click Add... Enter the following: Source module: jdk.compiler Package: com.sun.tools.javac.tree

Setting JAVA_HOME when running Ant from Java

谁都会走 提交于 2019-11-30 15:19:49
The reason is long and boring, but I need to run an Ant script to compile Java 1.5 code from a Java 1.4 app. I keep getting this error, though: BUILD FAILED build.xml:16: 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:\j2sdk1.4.2_16\jre" In my code, I have: Project p = new Project(); p.setUserProperty("ant.file", buildFile.getAbsolutePath()); p.setProperty("java.home", "C:\Program Files\Java\jdk1.6.0_04"); p.fireBuildStarted(); p.init(); // so on and so forth but it ignores it. I've also

How can i make gitbash find the javac command?

I made my gitrepository and committed it. Inserted one java-file and wanted to to compile it ,but it gave me this: Bernard@BERNARD-PC /c/users/bernard/desktop/git2 (master) $ javac TestGUI.java sh.exe": javac: command not found It used to work in school on their computer,but at home on my laptop I cant make it work. EDIT : I added javac as environment variable: EDIT : Short term solution for the duration of the runtime of gitbash enter: `export PATH=$PATH:"/C/Program Files/Java/jdk1.7.0_21/bin/"` Long term solution so you can reuse this command after shutting down and rebooting gitbash: (for

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I'm looking for the source code of Sun's standard java compiler, javac . jdk1.6.0_07 has a few classes that are related, but they are interfaces ( java.lang.Compiler and javax.tools.JavaCompiler ). There's also some packages under com.sun.mirror.* and com.sun.source.* , which seem to be interfaces for

Annotation Processor, generating a compiler error

孤者浪人 提交于 2019-11-30 12:01:29
问题 I'm trying to create a custom annotation that, for example, ensures that a field or method is both public and final , and would generate a compile time error if the field or method is not both public and final , as in these examples: // Compiles @PublicFinal public final int var = 2; // Compiles @PublicFinal public final void myMethod {} // Compile time error @PublicFinal private final int fail = 2; So far, I've made both the custom annotation interface: import java.lang.annotation.Documented
