javac Java Compiler Memo

-d option defines generated class file path

-d classpath sourcefile

Met errors.

  • Permission error of external jar files -> change permission from eclipse file property
  • javac: invalid flag:error -> quotation solved this (when I used wild * card)

 

collect statement for compile eclipse project programs

javac -d /home/masa/Desktop/build-test -cp src/jaydle/*;resources/mp3agic-0.9.2-SNAPSHOT.jar;resources/jid3lib-0.6.1-SNAPSHOT.jar src/jaydle/Utilities.java

this case -cp ./ was not collect.

But still generating same errors to this post

This script wasn’t enough.

maybe classpath problem.

compile error cause of dependency class files.

[javac]warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

Add

<javac srcdir=”${src}” destdir=”${bin}” classpathref=”classpath” includeantruntime=”false>

solve this.

Below is a main error

error: cannot find symbol

 

Next

Error: Could not find or load main class jaydle.Main

occurred. This time Project > Clean solved this.

deleting launch configure files aren’t effective.

It seems my ant build.xml file collapsing the project file or classpath file.

This is being cause of this error.

When I checked .classpath file when Error: Could not find or load main class occurred,

lib, resource around naming is the cause.

Realized it’s all about java.awt.Event.ActionListener

eclipse compiler error output -> show view -> problems
This wasn’t useful.
How to see compiler error output??
And how to recompile with -Xdiags:verbose to get full output?

Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output

from

After this, I tried other projects, and had no problems so maybe import statements errors.

I’m trying to write my java build program.

But it also spitting errors…

Jaydle journal

  1. Bash scripts to Java processbuilder program migration.
  2. Add jmenubar and add action (used inner class)
  3. Implemented JFileChooser
  4. Implemented swingworker class doinbackground
  5. Object serialization to store save directory data
  6. Used system property variables for default save directory
  7. Initialize .ser file to store data.
  8. ID3Tag viewer implementation, using mpatric mp3agic
  9. Used jtable to display id3 tags
  10. Windows YouTube-dl execution program write but it needs ffmpeg to extract audio, this is not done
  11. Wrote JaydleMusicManager which can handle MP3 files ID3 tags and move other directory
  12. Put in order eclipse project file (not pushed to GitHub yet)

JavaSound教科書 赤間世紀著: メモ

最初のサンプルプログラム2個ちゃんと動作してないのなんでだろ。

clip使ったプログラム、音源が最後まで再生されない。

レコーダーは動いたけど。

サポートページに載っているかな。。。

その後

動くよう修正した。

masa – masa – Clip01としてワークスペースに保存

getFrameLength()とgetMicrosecondLength()を試した。

最後まで流すのにgetMicrosecondLengthの返り値を使った。適切に繰り上げしないとなぁ。

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:compileDebugJavaWithJavac'. at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:103) at org.gradle.api.internal.

From the solvent start, set proper path of JDK was effective.
I also downloaded other SDK version for each Android version.

 

Other error message.

Edit Configuration: Error Please select Android SDK

I Logged in to Google Account

Installed many SDK versions and Tools from SDK Manager icon on Android Studio.

Right upper icon on Android Studio – Project settings (icon) > change JDK to /usr/lib/jvm/1.8

I guess my case was cause of JVM path.
Perhaps SDK was only latest one, I downloaded even the oldest one.
It expanded to 11.9GB…

Solved this !!!

 

Next execute on my tablet.

My Ubuntu didn’t recognize my tablet.

installed adb

make sure the tablet’s

developer options > usb debugging on

Use sudo usermod -aG plugdev $LOGNAME to add yourself to the plugdev group about adb command.

cd to ..

masa@em-p:~/Android/Sdk/platform-tools$ ./adb devices
List of devices attached
adb server version (32) doesn’t match this client (40); killing…
* daemon started successfully

Changed cable.
restart tablet and ubuntu resolved this.
Often usb debugging mode is don’t know why..

Jaydle Development Journal:JA(va) Y(outube)D(l)-E(xtended)

I’m going to make post about note of jaydle development.
This is program which enhance youtube-dl command.

First I made prototype in bash.

It can download simultaneously and can download by just search keywords.
E.G

“jaydle -keywords tsunami disasters”

will downloads result videos top 10 automatically.
And I have numbering option from the top search result.
So you can know the order of search result after downloading.

But this shell script needing edit somehow. LoL.

I’m planning to make public journal of Jaydle development. e.g. Implementing SwingWorker, Menu bar, Serialization of the store path, …

So watching me!!!

Windows Administrating: Install OpenJDK 1.8

To begin from the result had to uninstall old Oracle jdk (1.6) to use Openjdk 1.8 because of priority problem I guess. But it made can’t open jar file by double click the file…

So if you will, take responsibillity…

Today I installed Eclipse Oxygen to clean installed Windows 7 on NEC LaVie laptop which I call “dee-jay” because this is for Traktor DJ.

And when lauching Eclipse it said like “Need newer JDK than 1.6”.
So I downloaded the source from here.
https://jdk.java.net/java-se-ri/8

Here I heard “Windows i586” for the first time.
But it was not problem so. Just CPU architecture (guess old).

After downloaded the zip extracted to “Program Files” directory.
And added the path to “Environmental Variables”.
But it kept using 1.6 JDK.
Configuring “JAVA_HOME” environment variable was not effective too.

Finally I uninstalled old “Oracle JDK 1.6” from the “Control Panel” > “Uninstall Softwares”.
This was great. 1.6 jdk was at “System32” directory whereis high priorities.

I used

start — this start programs in the search path.
path — this displays path variable values.
(setx path “%path%; this is useful to set path variable)

commands on Command prompt.

And now fighting to Clone git repository on eclipse LoL.

Programming column: A programming unified viewand

My case fun of programming started from bash script. Was really wanted to accustomed with unix or Linux culture bought tons of unix used books mainly under $10.. lol.

Before that I learned Java but it’s hard to living well with OS ( computing environment). Especially make files, directories, reading, writing, using regular expression and co-operating with environment.

Bash is perfect for co-work with the environments. But not Object Oriented so hard to code maintain and manage.

Once you got through one bash book ( My case O’reilly’s “Learning bash shell” Second edition maybe) u will be interested in Sed & Awk.

Sed is “Stream EDitor” by my memory. This using ed text editor inside might be? Ed is very old text editing program. AT&T Bell Lab’s product. Line orient and matrix(mother) of Vi text editor. It won’t even display whole text. 🤓 Because it’s for printer type display(teletype). In the era no crt display and printed to papers. So this was efficient for paper printer.

Awk is acronym for “Adrian will kome “. 🤕

This is splendid language, Jon Bentley was attracted . Perl’s main influencer..

Python is made by masters of low or middle level languages. There are tons of splendid libraries, functions and programming style guide lines.

The point of the view rom function builder on Java, python or frameworks like angular are built arts by the hackers.

Now they must be loving Arduino or Raspy because that’s EECS “Ying and Yang”.

Compiler knowledge is essential.

 

Almost Unix commands are written in C.
But those are very small programs. Like things between programs and API.
Programming approach history is getting generality as it in mathematical description.
Unix commands are more like organic, C? Lol.
I thought like this when reviewing Grep command usage and bash programming.

To be continued,,,

Eclipse error:Editor does not contain a main type or cannot be resolved to a type

eclipse error.jpeg

 

To begin from the cause and solve method…

serObj=load("jaydle.ser");

This statement causes all errors which eclipse said “cannot be resolved to a type” or something like that error.

It highlighted as red circle X, and the others are red light objects.
It said all of my original objects in the class are “cannot be resolved to a type” or something wrong.

From terminal (command line), I tried to compile and error occurred, it pointed

masa@em-p:~/Public/git/jaydle-project/jaydle-project$ javac src/jaydle/JaydlePrototype.java 
src/jaydle/JaydlePrototype.java:61: error: <identifier> expected
serObj=load("jaydle.ser");

So commented out the line,

all of errors disappeared and Mose came. lol.

 

I tried configure “Java build path” but it wasn’t effective.

Eclipse configuration is hard. And error detective system this case reverse effected….

See you!
